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 by change of core acceptor unit. Photovoltaic parameters were estimated with respect to PBT7 and PSBBT as donor. All compound showed better performance with PSBBT as compare with PBT7. Compound 2 showed superior charge transporter properties as compare to other compounds.
