A series of well-defined D–π-B–A C60 adducts containing three chromophores and their corresponding precursors were facilely developed as organic photovoltaic materials. The photophysical and electrochemical properties indicated that effective photo-induced intramolecular and/or intermolecular energy transfer and charge transfer were formed from the donor chromophores to the C60 moiety in thin films. Solution processed molecular heterojunction solar cells using 12 as active layer were fabricated with 2.0% monochromatic efficiency. Our results showed that further exploration might lead the way toward high-efficient solution-processed single molecular solar cell materials based on conjugated oligomer covalent to fullerene units.
