Lam, Jacky Tang, Ben Zhong Regio- and Stereoselective Polymerization of Diynes with Inorganic Comonomer: A Facile Strategy to Conjugated Poly(<i>p</i>‑arylene dihalodiene)s with Processability and Postfunctionalizability Development of new methodologies for synthesizing polymers with novel structures and unique properties is a fundamentally important area in polymer science. Herein, a novel synthetic strategy to conjugated poly­(<i>p</i>-arylene dihalodiene)­s (PADs) with high regio- and stereoselectivity was developed. In the presence of PdBr<sub>2</sub> and CuBr<sub>2</sub>, the polymerizations of terminal alkynes proceeded smoothly in air without heating to generate PADs in high yields (up to 95.3%) with high molecular weights (<i>M</i><sub>w</sub> up to 915 900). Low-cost inorganic CuBr<sub>2</sub> played dual roles as cocatalyst and comonomer. The PADs possessed good solubility and film-forming ability. Their thin films exhibited high refractive indices (1.7149–1.7245) and would be fabricated into well-resolved fluorescent photopatterns by photolithography. Thanks to the vinyl bromine functionality, the PADs could undergo efficient postmodification to afford polymers with more sophisticated structures and applications. polymer;arylene;vinyl bromine functionality;CuBr 2;dihalodiene;PAD 2018-04-27
