Diketopyrrolopyrrole based compound with multiple donor–acceptor unit were designed and synthesized. Different electron-deficient groups are insert as core and wide range of HOMO and LOMO energy levels are attained. It was analyzed that how core acceptor affects electronic, optical, photovoltaic and charge transfer properties. Findings indicate that electronic and optical behavior significantly affected...
Three new diketopyrrolopyrrole based compounds with Acceptor-Donor-Acceptor-Donor-Acceptor (A-D-A-D-A) skeletons were designed and synthesized through varying the electron-deficient core from diphenylquinoxaline (DP-Qx), thieno[3,4-c]pyrrole-4,6-dione (DP-TPD) to 2-dodecyl-6,7-diphenyl-2H-[1,2,3]triazole[4,5-g]quinoxaline (DP-TQx). We have calculated and studied the effect of central acceptor units...
