摘要: Abstract Two new conjugated acceptor–donor–acceptor (A–π-D–π-A) compounds having a Zn-porphyrin acting as donor and linked by ethynylenes to one or two units of thienylenevinylene capped dicyanovinylene groups acceptor have been synthesized their photophysical electrochemical properties were investigated. These used materials PC61BM PC71BM acceptors in solution-processed bulk-heterojunction (BHJ) organic solar cells the best photoconversion efficiency (PCE) obtained was 3.21%.
