Abstract
Two new high-performance DPP-containing donor molecules employing a molecular architecture with three DPP chromorphores (tri-DPP) in conjugated backbones are synthesized and characterized. The two tri-DPP molecules with only a structural difference on alkyl substitutions, when blended with PC71 BM, lead to power conversion efficiencies up to 4.8 and 5.5%, respectively.
摘要
两种新型高性能含 DPP 的给体分子，采用具有三个 DPP 发色团（三 DPP）共轭主链的分子结构，已被合成并加以表征。这两种三 DPP 分子，仅在烷基取代基上有结构差异，当与 PC71BM 共混时，分别实现高达 4.8%和 5.5%的功率转换效率。
