Synthesis and photophysical properties of donor-acceptor flavone-based derivatives with good aggregation-induced emission characteristics

Four novel compounds (1-4) were synthesized using 2-phenyl-4H-1-benzopyran-4-one (flavone) moiety as an acceptor and phenoxazine, phenothiazine, 9,9-dimethyl-9,10-dihydroacridine, diphenylamine as donors. Their photophysical properties were studied with spectroscopic and theoretical methods. The results show that 1 and 2 exhibit good aggregation-induced emission (AIE) properties in tetrahydrofuran (THF)/water mixtures, whose maximum photoluminescence (PL) intensities are 156- and 187-fold higher than those in pure THF solutions, and can reach 256- and 506-fold higher than those in the mixtures at water fractions of 50%, respectively. 3 displays similar PL property except for obvious emission in pure THF solution. However, PL intensity of 4 decreases with an increase in water fraction, and then is enhanced with further increase in water fraction. Moreover, 4 shows high quantum yields both in toluene solution (0.61) and in solid state (0.83). It exhibits a positive sol-vatochromism. In addition, 2 possesses mechanofluorochromic transition from sky blue to yellow after grinding. It can also be applied in live-cell imaging.

Design and synthesis of herboxidiene derivatives that potently inhibit in vitro splicing

Herboxidiene is a potent antitumor agent that targets the SF3B subunit of the spliceosome. Herboxidiene possesses a complex structural architecture with nine stereocenters and design of potent less complex structures would be of interest as a drug lead as well as a tool for studying SF3B1 function in splicing. We investigated a number of C-6 modified herboxidiene derivatives in an effort to eliminate this stereocenter and, also to understand the importance of this functionality. The syntheses of structural variants involved a Suzuki-Miyaura cross-coupling reaction as the key step. The functionalized tetrahydrofuran core has been constructed from commercially available optically active tri-O-acetyl-d-glucal. We investigated the effect of these derivatives on splicing chemistry. The C-6 alkene derivative showed very potent splicing inhibitory activity similar to herboxidiene. Furthermore, the C-6 gem-dimethyl derivative also exhibited very potent in vitro splicing inhibitory activity comparable to herboxidiene.

Multicompartment Self-assemblies of Triblock Copolymer for Drug Delivery

Novel multicompartment self-assemblies of triblock copolymer polystyrene-polyisoprene-poly(2-vinylpyridine) (PS-PI-P2VP) for drug delivery are demonstrated. The triblock copolymer assemblies in dilute solutions in a common solvent (tetrahydrofuran) undergo transformations from core-shell-corona micelles to multicompartment micelles by adding P2VP-selective solvent (water). The effects of water content and pH on the assembled structures were systematically investigated. Multicompartment micelles are also obtained by adding a surfactant, 4-biphenylcarboxylic acid, into the solution. Such multicompartment self-assemblies are used as carriers for encapsulation and release of an anticancer drug doxorubicin hydrochloride (DOX). The drug loading content and drug loading efficiency of DOX were evaluated. The DOX release experiments were performed at 37 degrees C under pH 5.5 and pH 7.4. The DOX release rate was improved as pH decreased from pH 7.4 to 5.0, with 45.6% release of DOX in 32 h.

Single-Step Integration of Poly(3-Octylthiophene) and Single-Walled Carbon Nanotubes for Highly Reproducible Paper-Based Ion-Selective Electrodes

Calibration of ion-selective electrodes (ISEs) is cumbersome, time-consuming, and constitutes a significant limitation for the development of single-use and wearable disposable sensors. To address this problem, we have studied the effect of ion-selective membrane solvent on ISE reproducibility by comparing tetrahydrofuran (THF) (a typical solvent for membrane preparation) and cyclohexanone. In addition, a single-step integration of semiconducting/transducer polymer poly(3-octylthiophene) (POT) with single-walled carbon nanotubes (SWCNTs) into the paper-based ISEs (PBISEs) substrate was introduced. PBISEs for potassium and sodium ions were developed, and these ISEs present outstanding sensor performance and high potential reproducibility, as low as +/- 1.0 mV (n = 3).

Novel pyrazolyl-thiazoles: synthesis, characterization and study of their antidiabetic properties

A novel series of 1,3-diphenyl-pyrazole-4-carboxylic acid and its thiazole derivatives were conveniently synthesized followed by coupling reaction to investigate their efficiency as alpha-amylase and alpha-glucosidase inhibiting agents. Initially, pyrazole esters were obtained by using various benzaldehydes as precursor and subsequently converted to respective acids in tetrahydrofuran solvent medium. All the acid key intermediates obtained were coupled with previously synthesized thiazole amines to yield title compound with good yield. The current attempt cultivated many advantages such as good yield, time quenching and easy work up. Structures of newly obtained compounds were characterized by spectral studies such as NMR, Mass, IR and elemental analytical techniques. Finally, all the prepared compounds were tested for their antidiabetic activity. Among the synthesized compounds in comparison with standard drug, compound 4c, 4e and 4j showed promising in vitro antidiabetic activity. Bioassay result suggest that the compound 4e may emerge as a potent antidiabetic agent in future drug design.

Tetrahydrofuran-based two-step solvent liquefaction process for production of lignocellulosic sugars

Large-scale production of biofuels and chemicals will require cost-effective, sustainable, and rapid deconstruction of woody biomass into its constituent sugars. Here, we introduce a novel two-step liquefaction process for producing fermentable sugars from red oak using a mixture of tetrahydrofuran (THF), water and dilute sulfuric acid. THF promotes acid-catalyzed solubilization of lignin and hemicellulose in biomass achieving 61% lignin extraction and 64% xylose recovery in a mild pretreatment step. The pretreatment opens the structure of biomass through delignification and produces a cellulose-rich biomass, which is readily solubilized at low temperature giving 65% total sugar yields in a subsequent liquefaction process employing the same solvent mixture. This process achieves competitive sugar yields at high volumetric productivity compared to conventional saccharification methods. THF, which can be derived from renewable resources, has several benefits as solvent including ease of recovery from the sugar solution and relatively low toxicity and cost.

Molecular weight effect on the structural detail and chain characteristics of 33-armed star polystyrene

In this study, synchrotron X-ray scattering and quantitative data analysis were performed on a series of 33-armed polystyrenes with four different arm molecular weights in cyclohexane (CHX, Theta solvent) and tetrahydrofuran (THF, good solvent). The quantitative scattering analysis was successfully done, providing molecular structure details and their responses to the solvent change. Each star system is confirmed to be prepared in a very narrow unimodal size distribution; the distribution is slightly broadened with increasing the arm molecular weight. It has an oblate ellipsoid shape, which is composed of two phases, a denser and smaller core and a less dense and thicker fuzzy shell; the ellipsoidicity ranges in 0.56-0.62. The core and shell phases are enlarged and thickened respectively by the arm molecular weight increases. Both the phases are further expanded in THF. Interestingly, the THF-induced expansion is predominant in the core against the fuzzy shell with a Gaussian like density gradient. Overall, the 33-armed star polystyrenes in various molecular weights are quite unique in the structural details and performance in solvent changes, which would be beneficial for advanced applications in various technological areas including smart deliveries of desired molecules (drug, gene, imaging agent, etc.).

Diversiform Nanostructures Constructed from Tetraphenylethene and Pyrene-Based Acid/Base Controllable Molecular Switching Amphiphilic [2]Rotaxanes with Tunable Aggregation-Induced Static Excimers

Dual-emissive tetraphenylethene (TPE) and pyrene-containing amphiphilic molecules are of great interest because they can be integrated to form stimuli responsive materials with various biological applications. Herein, we report the study of mechanically interlocked molecules (MIMs) with aggregation-induced static excimer emission (AISEE) property through a series of TPE and pyrene-based amphiphilic [2]rotaxanes, where t-butylcalix[4]arene with hydrophobic nature was used as the macrocycle. Evidently, by adorning TPE and pyrene units in [2]rotaxanes P1, P2, P1-b, and P2-b, they display remarkable emission bands in 70% of water fraction (f(w)) in tetrahydrofuran (THF)/water mixture, which could be attributed to the restricted intramolecular rotation of phenyl groups, whereas prominent blue-shifted excimer emission of pyrene started to appear as f(w) reached 80% for P1 and 90% for P1-b, P2, and P2-b, which was ascribed to the favorable pi-pi stacking and hydrophobic interactions of the pyrene rings that enabled their static excimer formation. The well-defined distinct amphiphilic nanostructures of [2]rotaxanes including hollowspheres, mesoporous nanostructures, spheres, and network linkages can be driven smoothly depending on the molecular structures and their aggregated states in THF/water mixture. These fascinating diversiform nanostructures were mainly controlled by the skillful manner of reversible molecular shuttling of t-butylcalix[4]arene macrocycle and also the interplay of multinoncovalent interactions. To further understand the aggregation capabilities of [2]rotaxanes, the human lung fibroblasts (MRC-5) living cell incubated with either P1, P2, P1-b, or P2-b was studied and monitored by confocal laser scanning microscopy. The AISEE property was achieved at an astonishing level by integrating TPE and pyrene to MIM-based reversible molecular switching [2]rotaxanes; furthermore, distinct nanostructures, especially hollowspheres and mesoporous nanostructures, were observed, which are rarely reported in the literature but are highly desirable for future applications.

Comparison of the Retention and Separation Selectivity of Aromatic Hydrocarbons with Polar Groups in RP-HPLC Systems with Different Stationary Phases and Eluents

In this manuscript, the retention of aromatic hydrocarbons with polar groups has been compared for systems with various nonpolar columns of the types from C3 to C18 and different mobile phases composed of methanol, acetonitrile, or tetrahydrofuran as modifiers. The selectivity separation of the solutes in systems with different adsorbents, when one eluent modifier is swapped by another, has been explained, taking into account molecular interactions of the solutes with components of the stationary phase region (i.e., extracted modifier depending on the chain length of the stationary phase).

Biobased Thermoplastic Elastomers: Structure-Property Relationship of Poly(hexamethylene 2,5-furanodicarboxylate)-Block-Poly(tetrahydrofuran) Copolymers Prepared by Melt Polycondensation

A series of poly(hexamethylene 2,5-furanodicarboxylate)-block-poly(tetrahydrofuran) (PHF-b-F-pTHF) copolymers were synthesized using a two-stage procedure, employing transesterification and polycondensation. The content of pTHF flexible segments varied from 25 to 75 wt.%. H-1 nuclear magnetic resonance (NMR) and Fourier transformed infrared spectroscopy (FTIR) analyses were applied to confirm the molecular structure of the materials. Differential scanning calorimetry (DSC), dynamic mechanical measurements (DMTA), and X-ray diffraction (XRD) allowed characterizing the supramolecular structure of the synthesized copolymers. SEM analysis was applied to show the differences in the block copolymers’ morphologies concerning their chemical structure. The influence of the number of flexible segments in the copolymers on the phase transition temperatures, thermal properties, as well as the thermo-oxidative and thermal stability was analyzed. TGA analysis, along with tensile tests (static and cyclic), confirmed the utilitarian performance of the synthesized bio-based materials. It was found that an increase in the amount of pTHF caused the increase of both number-average and weight-average molecular weights and intrinsic viscosities, and at the same time causing the shift of the values of phase transition temperatures toward lower ones. Besides, PHF-b-F-pTHF containing 75 wt.% of F-pTHF units was proved to be a promising thermoplastic shape memory polymer (SMP) with a switching temperature of 20 degrees C.
