Most importantly, the LUMO energies of PFCN are around 1 eV lower than those of PF, which results in the decrement of EA about 0.9 eV, indicating that the 1,2-bis( p -phenylene)-1-cyanovinylene unit has significantly improved the electron-accepting properties of the copolymer PFCN.
更重要的是，PFCN和PPhCN的最低空轨道比聚芴低近1 eV，直接导致电子亲和势降低0.9 eV。这意味着含氰基亚乙烯基共聚物的电子注入能力大大提高。
