Pd-catalysed oxidative C–H/C–H coupling homopolymerization of thiazole derivatives with different numbers (n = 1–3) of thiophene as bridged units was described. It represents a facile and practical methodology to prepare thiazole-based conjugated polymers in excellent yields. Three conjugated polythiazole derivatives (P1–P3) were synthesized by utilization of ligand-free Pd(OAc)2 as a catalyst in...
Electrochromic polymers are attractive materials with enormous potential in the rapidly developing area of plastic electronics due to their flexibility, low-power consumption, ease of processing and low processing cost. Electrochromic devices created with electrochromic polymers are likely to be alternatives or supplements to the conventional inorganic electrochromic devices, which face challenges...
This article describes the synthesis and characterization of microporous organic copolymers (PP-N-x, where “x” is the molar percent of triphenylamine) prepared from triphenylamine and dichloro-p-xylene using a combination of oxidative polymerization and Friedel–Crafts alkylation process promoted by anhydrous FeCl 3 . The samples possessed BET specific surface areas from 318 to 1530 m 2...
Two types of microporous polymeric networks have been prepared from monomers containing N-tert-butoxycarbonyl-protected pyrrole by FeCl 3 -mediated oxidative coupling polymerization. These materials were predominantly microporous (with BET surface areas of 828 m 2 g −1 and 1408 m 2 g −1 ), exhibiting high CO 2 uptake capacities (1.96 mmol g −1...
Novel conducting polypyrrole (PPy) films with microlens arrays (MLAs) were successfully fabricated by combination of breath figures (BFs) and replica molding methods. Polycarbonate (PC) molds prepared by BFs method contain concave cavities with a diameter of about 3–4 μm and a depth of about 2.5 μm in the center of the cavity as were revealed by scanning electron microscopy (SEM) and atomic force...
A series of comb-type amphiphilic copolymers (PES-g-PEO) with a stiff poly(aryl ether sulfone) backbone and flexible PEO side chains was synthesized via a “grafting onto” technique. By controlling the monomer feed ratios, high molecular weight copolymers with a range of PEO side chain content were prepared and used to form tough and flexible membranes. The PES-g-PEO membranes displayed high thermal...
Polycarbonate (PC) was blended with various loadings of novel phosphorus-containing thermotropic liquid crystalline copolyester named PHDDT to form the in situ reinforced composites (PC/PHDDT) by flake extrusion. The morphology, thermal behaviors, tensile properties and flame-retardant performances of PC/PHDDT composites were investigated. Results suggested that fine deformation and microfibrillation...
