mechanofluorochromic phenomenon of the N,N′-dialkylanthracene-1,8-dicarboxamide 1 (1,8-bis(N-alkylamide)anthracene) was observed due to the presence of the two amide groups at the 1,8-position of the anthracene ring, because the mechanofluorochromic behavior was not observed for the N-alkylanthracene-1-carboxamide 2 (mono(N-alkylamide)anthracene). Interestingly, changes in the luminous color of the ground samples
制备了几种类型的N,N'-二烷基蒽-1,8-二甲酰胺1和N-烷基蒽-1-甲酰胺2,并观察了它们在固态和溶液状态下的光物理性质。N,N' -Di - tert -butylanthracene-1,8-dicarboxamide 1e和N - tert -butylanthracene-1-carboxamide 2e 由于体积庞大,在固态下表现出稍高的荧光量子产率 ( φ f = 0.63–0.67)叔丁基。N,N'的机械荧光变色现象-dialkylanthracene-1,8-dicarboxamide 1 (1,8-bis( N - alkylamide)anthracene) 由于在蒽环的 1,8-位存在两个酰胺基团,因此观察到了机械荧光变色行为。未观察到N-烷基蒽-1-羧酰胺2(单(N-烷基酰胺)蒽)。有趣的是,在加热和用 CH 2 Cl 2蒸气发烟时,观察到研磨样品的发光颜色发生
