A perfluorinated perylene diimide, N,N‘-diperfluorophenyl-3,4,9,10-perylenetetracarboxylic diimide (DFPP), and its nonfluorinated analogue, N,N‘-diphenyl-3,4,9,10-perylenetetracarboxylic diimide (DPP), showed similar UV−vis absorption and fluorescence spectra when they existed as monomeric dyes in solutions, whereas in solid films they exhibited great differences. Absorption band splitting was observed
全氟苝二亚胺 N,N'-diperfluorophenyl-3,4,9,10-perylenetetracarboxy diimide (DFPP) 及其非氟化类似物 N,N'-diphenyl-3,4,9,10-perylenetetracarboxy diimide (DPP) ),当它们作为单体染料存在于溶液中时,显示出相似的紫外-可见吸收和荧光光谱,而在固体薄膜中,它们表现出很大的差异。观察到 DPP 薄膜的吸收带分裂;然而,对于 DFPP 薄膜,除了吸收峰变宽并转移到更长的波长区域外,类似于溶液中的吸收的精细结构仍然存在。此外,发现当基板温度升高到 200 °C 时,DFPP 分子聚集形成结晶膜。通过分子构象的模拟,
