Molecular design: Employing electro-copolymerization, we use benzodithiophene-S,S-tetraoxide (BDTT) as an electron acceptor to yield promising electronically conducting polymers (ECPs).

The alternating copolymers of carbon monoxide (CO) and vinyl arene monomers, namely aromatic polyketones, are a family attractive engineering plastic. In the catalytic synthesis this kind polymeric materials, [N,N] bidentate palladium catalysts represent most successful systems. review, we introduce present status polyketone synthesis, with focus on polyketones made from CO. We also address pal...

We found that a cationic hetero tetranuclear complex including calcium and three cobalts exhibited high catalytic activity toward alternating copolymerization of propylene oxide (PO) carbon dioxide (CO 2 ).

Although the copolymerizations of l-lactide (LA) with seven- or six-membered ring lactones have been extensively studied, the copolymerizations of LA with four-membered ring lactones have scarcely been reported. In this work, we studied the copolymerization of LA with β-propiolactone (PL) and the properties of the obtained copolymers. The copolymerization of LA with PL was carried out using tri...

We report herein the synthesis and characterization of 9-(2-diallylaminoethyl) adenine. We evaluated two different synthetic routes starting with adenine where the optimal route was achieved through coupling of 9-(2-chloroethyl)adenine with diallylamine. The cyclopolymerization and cyclo-copolymerization of 9-(2-diallylaminoethyl)adenine hydrochloride salt resulted in low molecular weight oligo...

The crystalline stereocomplexed polycarbonates can be prepared by mixing enantiopure polymers with opposite configuration, which derived from the asymmetric copolymerization with CO2 using enantiopure catalyst or/and chiral epoxides. Herein, we develop a powerful strategy for producing crystalline intramolecular stereocomplexed polycarbonates from racemic catalysts, which possess similar therma...

We developed the novel polymeric prodrugs synthesized by mechanochemical solid-state copolymerization of glucose-based polysaccharides (dextran orglycogen) and the methacryloyloxy derivative of 5-fluorouracil (5-FU). The copolymerization proceededreadily and each polymeric prodrug was quantitatively obtained within8 h reaction. The number average molecular weight (Mn) and polydispersity (H) of ...

A structurally well-defined THF-free cationic half-sandwich scandium aminobenzyl complex serves as a novel catalyst for the first copolymerization of 1-hexene with dicyclopentadiene to give the random copolymers with a wide range of 1-hexene contents (32-70 mol%) unavailable previously.

Branched phosphazenium salts are tested as alternative cocatalysts to traditional PPNX in the CO 2 /epoxide copolymerization with different catalysts. Higher molecular weights and comparable or superior conversions selectivities achieved.

This mini-review focuses on recent advances on the synthesis, structure, and characterization of allyl-based rare earth organometallic complexes, with emphasis on their ability to catalyze the polymerization of non-polar monomers such as conjugated dienes, styrene, and their related copolymerization.
