新型有机电子受体氟代苝酰亚胺的合成与表征

Synthesis and Characterization of a Novel Electron Acceptor——Fluoroperylene Diimide

设计和合成了一种新型有机电子受体 N ,N′-二 (五氟代苯基 ) -3 ,4,9,1 0 -四羧基二酰亚胺( DFPP) ,利用傅里叶红外光谱和核磁共振谱等方法表征了 DFPP的分子结构 ,用紫外 -可见吸收光谱、循环伏安法和电子自旋共振谱等手段证明了 DFPP中极低的最低未占有轨道 ( LUMO)能级为 -4.3 7e V.另外 ,还发现了 DFPP薄膜的独特聚集态结构 。

A novel electron acceptor, N,N′ diperfluorophenyl 3,4,9,10 perylenetetracarboxylic diimide (DFPP) with a good solubility and a high electron affinity was designed and prepared. Its molecular structure was characterized by FTIR and NMR measurements. As demonstrated by UV Vis, CV and ESR, the DFPP possessed much lower lowest unoccupied molecular orbital(LUMO) energy level of -4 37 eV, and the radical anion of DFPP could exist stoadily in the solution of DFPP in DMF because multiple strong ele...
