Synthesis of novel copolymer with 2,1,3-benzothia dizole structure in main chain

Copolymer with 2,1,3-benzothiadizole structure in main chain had been successfully synthesized through palladium-catalyzed triple-bond cross-coupling polycondensation method. The copolymer exhibited good solubility in common organic solvents such as CHCl_3, CH_2Cl_2 and THF. The polymer showed absorption spectra with maximum peak at 424 nm and 510 nm in solution and the spectral response were extended up to 630 nm. The band gap of the copolymer was estimated to be 1.96 Ev,which suggested its potential applications for organic solar cells.
