Synthes is and light-emitting porperties of an anthrancene-containing hyperbranched poly(aryleneethyny lene)
关键字：hyperbranched polymer, cross-coupling, blue light emission
Many light-emitting molecules and polymers are highly emissive in their dilute solutions but become weakly luminescent when fabricated into thin films. This is believed to be caused by aggregate formation: in the solid state,&nbs...

Anionic Copolymerization of Carbonyl Sulfide with Epoxides via Alkali Metal Alkoxides
关键字：carbonyl sulfide, copolymerization, alkali metal alkoxides, sulfur-containing polymer
Carbonyl sulfide (COS), an analogue of carbon dioxide (CO2), can be converted to CO2 via the carbonic anhydride enzymes widely existing in nature. COS is an ideal monomer for making poly(monothiocarbonate)s, which are difficult to synthesize by traditional methods. Herein, for the first time, we describe an anionic copolymerization of COS with epoxides using alkali metal alkoxides as the catalys...

Soluble N-substituted poly(benzimidazole imide)s via C-N coupling reaction
关键字：N-substituted poly(benzimidazole imide)s; heat-resistant polymer; C?N coupling reaction; good solubility
Novelheat-resistantN-substitutedpoly(benzimidazole imide)s (PBIIs)withgoodsolubilitywere synthesized via aC?Ncoupling reaction. A model reaction was carried out to assist in determining the optimal reaction conditions for the polymerization and to elucidate the chemical structures of the polymers. The structures of the resulting polymers were characterized by means of Fourier transform infrared ...
