制备了苯基甲苯基二苯并富烯(phenyltolyldibenzofulvene,1)并研究了其发光性能.化合物1具有聚集诱导发光(aggregation induced emission,AIE)及结晶诱导荧光增强(crystallization enhanced emission,CEE)的性质,且化合物1可形成蓝色、蓝绿色荧光的晶体以及黄绿色荧光的无定形态.因化合物1分子为扭曲的螺旋桨构象,分子在聚集态中以较疏松的形式堆积,故化合物1可在热、溶剂气氛以及外力刺激下发生多种聚集态间的可逆转变,从而实现在三种不同发光状态间的可逆转变.我们尝试将化合物1用于光学记录,以单一化合物1为发光材料,其可在蓝绿及蓝色荧光颜色背景上以暗黄绿色字迹记录,可通过研磨、加热及溶剂气氛处理擦除字迹,并将记录纸分别转变为蓝色、蓝绿色及黄绿色,因此化合物1有望用于光存储材料.
Phenyltolyldibenzofulvene (1) was prepared and its luminescent properties were studied.Compound 1 has the properties of aggregation induced emission (AIE) and crystallization enhanced emission (CEE) , And Compound 1 can form blue, blue-green fluorescent crystals and yellow-green fluorescent amorphous state.Compound 1 is in a distorted propeller conformation and the molecules accumulate in a more loose form in the aggregated state, Reversible transformation among various aggregation states under the conditions of heat, solvent atmosphere and external force stimulation, so as to achieve reversible transformation among the three different luminescent states.We try to use the compound 1 for optical recording, with a single compound 1 as the luminescent material, which Recorded in dark yellow-green on blue-green and blue fluorescent color backgrounds, erasing can be erased by grinding, heating and solvent atmosphere and the recording paper is converted to blue, cyan and yellow, respectively, thus Compound 1 Is expected for optical storage materials.
