According to recent research from Hongo, Japan, "Three kinds of diketopyrrolopyrrole-based donor-acceptor (D-A) type copolymers, poly{9,9-di(2-ethylhexyl)fluorene-2,7-diyl-alt-3,6-dithien-2-yl-2,5-di(2-ethylhexyl)-pyrrolo[3,4-c]pyrrole-1,4-dione-5',5 ''-diyl} (PF-DTDPP), poly{N-(1-decylundecyl)carbazole-2,7-diyl-alt-3,6-dithien-2-yl-2,5-di(2-ethylhexyl)-pyrrolo[3,4-c]pyrrole-1,4-dione-5',5 ''-diyl} (PC-DTDPP), and poly{N-[1-(2-ethylhexyl)-3-ethylheptanyl]-dithieno[3,2-b:2',3'-d]pyrrole-3,6-dithien-2-yl-2,5-di(2-ethylhexyl)-pyrrolo[3,4-c]pyrrole-1,4-dione-5',5 ''-diyl} (PDTP-DTDPP) were synthesized. By changing the donor segments, the absorption ranges of DTDPP-containing ...
