Thermosets containing benzoxazole units: Liquid-crystalline behavior and thermal conductivity

A series of liquid-crystalline (LC) thermosetting monomers containing benzoxazole (BO) units were synthesized to evaluate the thermal conductivities (lambda) of their cured resins. A BO-containing bisnadiimide system showed LC behavior during the heating process. However, the thermal cure of the bisnadiimide provided a film without optical anisotropy; consequently, the cured film exhibited normal levels of thermal diffusivity (alpha) and thermal conductivity (lambda). The disappearance of the optically anisotropic ordered structures during thermal curing is likely related to the temperature gaps between the cure reaction ranges and LC ranges (T-cure-T-LC gap). In addition, epoxy resins consisting of bisepoxides and BO-containing diamines were investigated because of their high flexibility in terms of molecular design that can be used to reduce the T-cure-T-LC gap. The combination of a terephthalylidene-type bisepoxide and BO-containing diamine with a controlled flexible chain length resulted in the smallest T-cure-T-LC gap among the epoxy resin systems examined herein. The cured epoxy resin film exhibited an appreciably increased lambda value (0.257 W m(-1) K-1) in the Z direction. This indicated the importance of the T-cure-T-LC gap for enhancing the alpha and lambda values of the cured films. This epoxy resin system was cured under a continuous DC electric field during polarizing optical microscopy. A prompt response with deformation of the LC domains was observed in harmony with temporal ON/OFF switching of the DC power supply. As expected, the cured film exhibited a significantly enhanced lambda value (0.488 W m(-1) K-1) in the Z direction.

Endogenous X-C=O species enable catalyst-free formylation prerequisite for CO(2)reductive upgrading

CO2, the main component of greenhouse gas, is currently developed as a promising surrogate of carbon feedstock. Among various conversion routes, CO(2)undergoing catalytic reduction can furnish hydrogen/energy carriers and value-added chemicals, while specific metal-containing catalysts or organocatalysts are often prerequisite for smooth proceeding of the involved reaction processes. In this work, both formic acid and N-containing benzoheterocyclic compounds (including various benzimidazoles, benzothiazole, and benzoxazole) along with silanols could be synthesized with high yields (>90%) from catalyst-free reductive upgrading of CO(2)under mild conditions (50 degrees C). The endogenous X-CO species, derived from theN-methyl-substituted amide-based solvent [Me2N-C(O)-R], especially PolarClean, andO-formyl group [O-C(O)-H] ofin situformed silyl formate, were found to play a prominent promotional role in the activation of the used hydrosilane for reductive CO(2)insertion, as demonstrated by density functional theory (DFT) calculations and isotopic labeling experiments. Moreover, reaction mechanisms and condition-based sensitivity assessment were also delineated.

A theoretical prediction about harnessing ESPT process for HBO derivatives

The different excited-state behaviors involved in excited-state proton transfer (ESPT) process of a series of 2-(2-hydroxyphenyl)benzoxazole (HBO) derivatives have been theoretically investigated. The primary bond lengths and bond angles were analyzed. Coupling with the infrared (IR) vibrational spectra, we confirmed that the intramolecular hydrogen bond O-HN should be strengthened in the S-1 state, which might provide the possibility for ESPT reaction, whereas introducing the fused rings may weaken the hydrogen bond in excited state. By investigating the vertical excitation process, the charge redistribution was explored. It is found that the electron-accepting -NO2 and -COOH would facilitate the ESPT reaction. With adding fused rings to HBO, less charge transfer exists in the transition process, which can reasonably explain the weakening hydrogen bond phenomenon in excited states. Via constructing the potential energy curves of both S-0 and S-1 states, we further confirm that electron-accepting substitutions could promote the ESPT process for HBO systems. And fused rings do inhibit ESPT reaction to a great extent. We believe this work not only elaborates the different excited-state proton transfer behaviors for a series of HBO derivatives but also presents a new harnessing ESPT process through substitutional effects.

Easily synthesizable benzothiazole based designers palladium complexes for catalysis of Suzuki coupling: Controlling effect of aryl substituent of ligand on role and composition of insitu generated binary nanomaterial (PdS or Pd16S7)

The present report is based on straightforward synthesis of molecular palladium complexes of benzothiazole based bulky ligands. Catalytic potential of 1 [Pd(L1)(2)Cl-2] and 2 [Pd(L2)(2)Cl-2] has been screened for Suzuki coupling. Due to structural difference between 1 and 2 (anthracen-9-yl in 1, and pyren-1-yl in 2), they behave as designers pre-catalysts and show different catalytic behaviour and nature by dispensing the nanoparticles of different materials (PdS by 1 and Pd16S7 by 2). This is an unprecedented observation as the size of the aryl substituent controls the efficiency (efficiency: 1 > 2) through determining the composition and nature of insitu generated nanoparticles.

Composite Ferroelectric Coatings Based on a Heat-Resistant Polybenzoxazole Polymer Matrix

The polycondensation of 5,5 -methylene bis(2-aminophenol) and the mixture of diamines 5,5 -methylene bis(2-aminophenol) and 4,4-(hexafluoroisopropylidene)dianiline (molar ratio 0.8:0.2) with isophthaloyl dichloride was used to synthesize a new heat resistant binder of the composites for microelectronics: poly(o-hydroxyamide) (POA) and poly(amido-o-hydroxy amide) (POA-F). The thermal stability of synthesized polymer coatings, as well as based on them photosensitive compositions with a naphthoquinondiazide photosensitive component were studied in the temperature range from 100 to 500 degrees C. Ferroelectric composites with nanodispersed lead titanate zirconate powder filler were formed based on these polymer matrices. By manipulating the conditions of the polymer formation, we obtained matrices with different stiffnesses, which reflected on the properties of the composite. The electrophysical parameters of the synthesized polymer and ferroelectric composite coatings were measured in the frequency range from 0.1 Hz to 1.5 GHz and the temperature range from 0 to 300 degrees C. The frequency and temperature stability of the dielectric constant of ferroelectric composite coatings up to 10 MHz and 300 degrees C, respectively, are noted. The influence of the composition and structure of the polymer matrix and the grain/matrix interfaces on the thermal stability of the dielectric parameters of composite films is estimated. The shift of the phase transition region toward higher temperatures in the composite structure, as well as the sufficient rigidity of the poly(benzoxazole) matrix, provide high temperature and frequency stability of the dielectric constant of the studied composites.

Co(II/III) Complexes with Benzoxazole and Benzothiazole Ligands as Efficient Heterogenous Photocatalysts for Organic Dyes Degradation

The problem of pollution in the current world is growing, however people’s awareness of environmental protection and ecology is also increasing. The aim of the study is to present three new Schiff base compounds with Co(II/III) ions and to assess their photocatalytic activity. The study was supported by cyclic voltammetry technique. In due course the complex 2 revealed as the most effective in AR18 degradation, even more than commercially available TiO2. The search for new photocatalysts able to decompose harmful organic dyes into environmentally friendly basic substances is becoming a new trend in the area of chemistry development.
