Nitrogen-phosphorus doped graphitic nano onion-like structures: experimental and theoretical studies

Onion-like graphitic structures are of great importance in different fields. Pentagons, heptagons, and octagons are essential features of onion-like graphitic structures that could generate important properties for diverse applications such as anodes in Li metal batteries or the oxygen reduction reaction. These carbon nanomaterials are fullerenes organized in a nested fashion. In this work, we produced graphitic nano onion-like structures containing phosphorus and nitrogen (NP-GNOs), using the aerosol assisted chemical vapor deposition method. The NP-GNOs were grown at high temperature (1020 degrees C) using ferrocene, trioctylphosphine oxide, benzylamine, and tetrahydrofuran precursors. The morphology, structure, composition, and surface chemistry of NP-GNOs were characterized using different techniques. The NP-GNOs showed diameters of 110-780 nm with Fe-based nanoparticles inside. Thermogravimetric analysis showed that NP-GNOs are thermally stable with an oxidation temperature of 724 degrees C. The surface chemistry analysis by FTIR and XPS revealed phosphorus-nitrogen codoping, and several functionalities containing C-H, N-H, P-H, P-O, P = O, C = O, and C-O bonds. We show density functional theory calculations of phosphorus-nitrogen doping and functionalized C-240 fullerenes. We present the optimized structures, electronic density of states, HOMO, and LUMO wave functions for P-doped and OH-functionalized fullerenes. The P = O and P-O bonds attributed to phosphates or hydroxyl groups attached to phosphorus atoms doping the NP-GNOs could be useful in improving supercapacitor function.

Construction of Metallacycle-Linked Heteroarm Star Polymers via Orthogonal Post-Assembly Polymerization and Their Intriguing Self-Assembly into Large-Area and Regular Nanocubes

.Summary of main observation and conclusion In recent years, synthesis of hybrid heteroarm star polymer with precisely defined arms has evolved to be one of the most attractive topics within polymer chemistry. In this study, we present the successful synthesis of metallacycle-linked heteroarm star polymers (HASPs) composed of crystalline poly(epsilon-caprolactone) (PCL) and polyacrylate (poly (N-isopropylacrylamide) (PNIPAM) segmentsviacombination of ring-opening polymerization (ROP) and reversible addition-fragmentation chain transfer (RAFT) controlled radical polymerization. Firstly, a hexagonal metallacycle containing three hydroxy groups and three chain transfer agent moieties at the alternative vertexes was designed and synthesized based on the general principle of coordination-driven self-assembly. Subsequently, upon combination of two orthogonal post-assembly polymerizations, a new family of HASPs containing a well-defined hexagonal metallacycle with precisely controlled position of polymer arms was facilely prepared. Interestingly, the obtained HASPs could spontaneously self-assemble into large-area and regular cubic nanoparticles in tetrahydrofuran (THF)/methanol (MeOH) mixed solvents under specific conditions as confirmed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). This study provides a simple route to the controllable preparation of HASPs, and opens up a new way for further study on self-assembly of different HASPs systems.

Formation of Three-Dimensional Electronic Networks Using Axially Ligated Metal Phthalocyanines as Stable Neutral Radicals

Organic pi-radical crystals are potential single-component molecular conductors, as they involve charge carriers. We fabricated new organic pi-radical crystals using axially ligated metal phthalocyanine anions ([M-III(Pc)L-2](-)) as starting materials. Electrochemical oxidation of [M-III(Pc)L-2](-)afforded single crystals of organic pi-radicals of the type M-III(Pc)Cl-2 center dot THF (M = Co or Fe, THF = tetrahydrofuran), where the pi-conjugated macrocyclic phthalocyanine ligand is one-electron oxidized. The X-ray crystal structure analysis revealed that M-III(Pc)Cl-2 formed three-dimensional networks with pi-pi overlaps. The electrical resistivities of Co-III(Pc)Cl-2 center dot THF and Fe-III(Pc)Cl-2 center dot THF at room temperature along thea-axis were 6 x 10(2)and 6 x 10(3) Omega cm, respectively, and were almost isotropic, meaning that M-III(Pc)Cl-2 center dot THF had three-dimensional electronic systems.

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.

Thin-Film Self-Assembly of Block Copolymers Containing an Azobenzene-Based Liquid Crystalline Polymer and a Poly(ionic liquid)

By combining reversible addition-fragmentation chain transfer (RAFT) with postfunctionalization and ion exchange, we synthesized a series of block copolymers (BCPs) containing an azobenzene-based liquid crystalline (LC) polymer (PAzo) and an imidazolium-containing poly(ionic liquid) (PIL, PVB(TFSI)) with the volume fraction of PIL (f(PIL)) values ranging from 15.9% to 69.9%. The samples obtained self-assemble into hexagonally packed cylinders (HEX), lamellae (LAM), and the mixed phase with coexisting HEX and LAM. The thin-film self-assembly of the samples PAzo(101)-b-PVB(TFSI)(22) and PAzo(101)-b-PVB(TFSI)(67) was studied systematically. We investigated the assembled structures of the thin films with various initial thicknesses after thermal annealing (145 degrees C for 12 h) or mixed solvent vapor annealing with tetrahydrofuran and n-hexane. Thin films with large-scale uniaxial PIL nanocylinders were obtained, which will greatly broaden the application of IL-based BCPs. Inverse phases were also observed for the thin films with thicknesses less than similar to 120 nm. The different mechanisms of the formation of inverse nanostructures formed in the thinner films under the thermal annealing and mixed solvent vapor annealing conditions were also elucidated.

Highly fluorescent bisboron complexes in both solution and solid-state: Synthesis, photophysical properties and lipid droplet imaging in living cells

A new family of pyrimidyl-enolate-based bisboron complexes (DB1-3) with intense fluorescence in both solution and solid-state has been developed. Although these complexes have a propeller-shaped structure, DB1-3 showed intense fluorescence in the diluted solution because of the efficient steric hindrance induced by phenyl rings. As a result, a very weak AIE effect was observed in the tetrahydrofuran-water binary solvents. Moreover, these complexes displayed highly efficient solid-state fluorescence with high quantum yields ranging from 32 to 55%. The relationship between the excellent photophysical properties of these complexes and their propeller-shaped structure was rationalized by single-crystal X-ray analysis. Utilizing the advantages of highly emissive in both solution and solid-state and good hydrophobicity, DB1-3 can target lipid droplets in living HeLa cells, which may be used as novel scaffolds for developing fluorescent LDs probes for investigating the related pathological processes.

The effects of graphene oxide nanosheets and Al2O3 nanoparticles on the kinetics of methane plus THF hydrate formation at moderate conditions

Gas hydrates, as a novel technology for storage and transportation of natural gases, have attracted many researchers. High pressures and low-temperatures demand, and slow kinetics of hydrates formation are the two critical challenges. In this study, mixed tetrahydrofuran (THF) and aluminum oxide nanoparticles (Al2O3) or graphene oxide (GO) nanosheets solutions were prepared, and their effects on the kinetics of methane hydrate formation were investigated. Also, the mechanism of hydrate formation in the presence of these nanoparticles is discussed. The concentrations in the systems were 5 and 15 wt% for THF, 100, 300, and 400 ppm for GO, and 0.2, 0.4, and 0.6 wt% for Al2O3. It is concluded that 15 wt%THF solutions decline the induction time, and promote the mole of consumed gas, rate of gas uptake, apparent rate constant of hydrate growth, storage capacity, and water to hydrate conversion comparing to 5 wt% systems. In addition, adding the nanoparticles to THF solutions declines the induction time, enhances the gas consumption during the initial minutes, and increases the rate of gas consumption, and the apparent rate constant of hydrate growth: however they have no significant effect on the final mole of gas consumed, storage capacity, and water to hydrate conversion.

Generation of highly amenable cellulose-I beta via selective delignification of rice straw using a reusable cyclic ether-assisted deep eutectic solvent system

Cellulolytic enzymes can readily access the cellulosic component of lignocellulosic biomass after the removal of lignin during biomass pretreatment. The enzymatic hydrolysis of cellulose is necessary for generating monomeric sugars, which are then fermented into ethanol. In our study, a combination of a deep eutectic (DE) mixture (of 2-aminoethanol and tetra-n-butyl ammonium bromide) and a cyclic ether (tetrahydrofuran) was used for selective delignification of rice straw (RS) under mild conditions (100 degrees C). Pretreatment with DE-THF solvent system caused similar to 46% delignification whereas cellulose (similar to 91%) and hemicellulose (similar to 67%) recoveries remained higher. The new solvent system could be reused upto 10 subsequent cycles with the same effectivity. Interestingly, the DE-THF pretreated cellulose showed remarkable enzymatic hydrolysability, despite an increase in its crystallinity to 72.3%. Contrary to conventional pretreatments, we report for the first time that the enzymatic hydrolysis of pretreated cellulose is enhanced by the removal of lignin during DE-THF pretreatment, notwithstanding an increase in its crystallinity. The current study paves way for the development of newer strategies for biomass depolymerization with DES based solvents.

Synthesis of Isonicotinic and Salicylic Acids Derivatives from (-)-alpha-Pinene and (+)-Delta(3)-Carene

Optically active cyclobutanediyl- and cyclopropanediylbisalkylidene dihydrazides of isonicotinic and salicylic acids were synthesized when the peroxide products of ozonolysis of (-)-alpha-pinene and (+)-Delta(3)-carene were reduced with isonicotinic and salicylic acid hydrazides in methanol, methylene chloride or tetrahydrofuran. Using QSAR models, high antituberculosis activity in combination with low values of acute toxicity and minimal inhibitory concentration was predicted for the obtained compounds.
