英文摘要	A series of novel low band gap polymers containing conjugated side chains with 4,7-dithien-5-yl-2,1,3-benzodiathiazole and different electron-withdrawing end groups of aldehyde (PT-DTBTCHO), 2-ethylhexyl cyanoacetate (PT-DTBTCN), 1,3-diethyl-2-thiobarbituric acid (PT-DTBTDT), and electron-donating end group of 2-methylthiophene (PT-DTBTMT) have been designed and synthesized. All polymers exhibit good solubility in common organic solvents, film-forming ability, and thermal stability. These conjugated polymers show the broad ultraviolet-visible absorption and the narrow optical band gaps in the range of 1.651.90 eV. Through changing the end group of conjugated side chains, the photophysical properties and energy levels of the polymers were tuned effectively. Bulk heterojunction solar cells based on the blend of these polymers and (6,6)-phenyl-C61-butyric acid methyl ester (PC61BM) reached the best power conversion efficiency (PCE) of 2.72%.
