The synthesis of a new series of conjugated dendrlmers based on an electron-accepting core is introduced. The compounds showed broad absorption bands over 300-700 nm and have reduced HOMO-LUMO gaps of 1.7-1.9 eV. Incorporation of these compounds In bulk heterojunction solar cells as electron-donating material along with PC61BM as electron acceptor gave power conversion efficiencies of up to 1.3% for the second-generation dendrimer.
