The ＂living＇/controlled radical polymerization （LRP） of styrene （St） at room temperature is rarely reported. In this work, copper（0） （Cu（0））-mediated radical polymerization of St at room temperature was investigated in detail. Dimethyl sulfoxide （DMSO）, N,N-dimethylformamide （DMF） as well as a binary solvent, tetrahydrofuravdl,l,l,3,3,3-hexafluoro-2- propanol were used as the solvents, respectively. Methyl-2-bromopropionate and ethyl 2-bromoisobutyrate were used as the initiators, respectively. The polymerization proceeded smoothly with moderate conversions at room temperature. It was found that DMF was a good solvent with the essential features of LRP, while DMSO was a poor solvent with uncontrollable molecular weights. Besides, the match among the initiator, solvent and molar ratios of reactants can modulate the livingness of the polymerization, and the proper selection of ligand was also crucial to a controlled process. This work provided a first example of Cu（0）-mediated radical polymerization of St at room temperature, which would enrich and strength the LRP technique.

A series of acceptor-donor-acceptor alternative small molecules were synthesized containing electron-donating central building moieties of phenothiazine, 2,7-carbazole and thieno[3,4-b]thiophene and electron-accepting moie- ties of tetrazine on both sides. The various conformations of the central blocks, with the coplanarity in an order of phenothiazine〈2,7-carbazole〈thieno[3,4-b]thiophene, have an obvious influence on the optical, electrochemical property and the crystallinity of small molecule. In addition, the blend films between small molecule and （6,6）-phenyl-C6rbutyric acid methyl ester offered significantly various morphologies, changing from uniform sur- face to interpenetrated networks. As a result, the bulk heterojunction photovoltaic devices based on the three small molecules provided varied performance, and the highest coplanar molecule based device exhibited the best photo- voltaic performance.
