Rational design of a novel indole-based microporous organic polymer: enhanced carbon dioxide uptake via local dipole–π interactions
关键字：indole-based microporous organic polymer, local dipole–p interactions
An indole-based microporous organic polymer (PINK) has been obtained by the condensation polymerization of 1,3,5-tris-(4-fluorobenzoyl)benzene with 3,30-diindolylmethane via a catalyst-free nucleophilic substitution reaction. Due to the local dipole–p interactions between indole and carbon dioxide (CO2), the uptake capacity for CO2 reaches up to 16.0 wt% (1.0 bar, 273 K), and the high (CO2/N2),...

Construction of Response Patterns for Metal Cations by Using a Fluorescent Conjugated Polymer Sensor Array from Parallel Combinatorial Synthesis
关键字：fluorescence, conjugated polymer, response pattern, sensor array, combinatorial synthesis
Pattern-based strategy is an emerging field of interest for effective sensing applications. Seven different conjugated polymers from combinatorial synthesis were combined into a sensor array, and seven metal cations were selected as representative analytes. The response patterns for each cation were constructed by collecting the individual fluorescence responses from seven...

A New Low-Bandgap Polymer Containing Benzene-Fused Quinoxaline: Significantly Enhanced Performance Caused by One Additional Benzene Ring
关键字：benzene-fused quinoxaline; low-bandgap; polymer solar cells
Two new alkoxy-substituted quinoxaline (Qx)-based copolymers, PBDTQx and PBDTPz, are
designed and synthesized. The only difference between these two polymers is that two methyl groups of the Qx are replaced by one additional fused benzene ring. The UV–Vis absorptions, thermal stability, energy levels, fi eld-effect carrier mobility, and photovoltaic characteristics of the two copolymers are sys...

Hemiphasmidic Side-Chain Liquid Crystalline Polymer: From Smectic C Phase to Columnar Phase with a Bundle of Chains as Its Building Block
关键字：Liquid Crystalline Polymer, Smectic, Columnar Phase C Phase,
We synthesized a new hemiphasmidic side-chain liquid crystalline polymer (P-n, n is the number of carbons in alky tail of the side chain, n = 4?12) using free radical polymerization. The side chain of P-n has a biphenyl in the middle, linked to the polystyrene backbone and to the terminal phenyl group with three alkyl tails via only methyleneoxy units. Upon increasing n,...

Influence from Thermal Elimination Temperature of Precursor Polymer and Film-forming Methods on the Photophysics of the Poly（2,5-didodecyloxy-p-phenylenevinylene）
关键字：poly（p-phenylenevinylene），synthetic methods，photophysics，polymer precursor，morphology
A series of poly（p-phenylenevinylene）s （PPVs） with good solubility were synthesized from thermal elimination of precursor poly（2,5-didodecyloxy-p-phenylenevinylene） at different temperature via Wessling method. The polymer photophysics were influenced by the thermal elimination condition, which was consistent with NMR and IR characterizations. The additional absorption peak at longer wavelen...

Journal of Polymer Science Part A: Polymer Chemistry 2012, 50(3), 571
关键字：controlled ring-opening polymerization (CROP); reversible addition-fragmentation chain transfer (RAFT); "living"/controllable polymerization; star block copolymer;
Reversible addition-fragmentation chain transfer (RAFT) polymerization is a more robust and versatile approach than other living free radical polymerization methods for synthesis of well-defined homo-, gradient, block, star-shaped and more complex structural polymers, like micro(nano)gels and polymer brushes. Thus the resultant polymers with thiocarbonylthio-terminated groups are readily tailored ...
