【摘要】：制備了苯基甲苯基二苯并富烯(phenyltolyldibenzofulvene,1)并研究了其發(fā)光性能.化合物1具有聚集誘導(dǎo)發(fā)光(aggregation induced emission,AIE)及結(jié)晶誘導(dǎo)熒光增強(qiáng)(crystallization enhanced emission,CEE)的性質(zhì),且化合物1可形成藍(lán)色、藍(lán)綠色熒光的晶體以及黃綠色熒光的無定形態(tài).因化合物1分子為扭曲的螺旋槳構(gòu)象,分子在聚集態(tài)中以較疏松的形式堆積,故化合物1可在熱、溶劑氣氛以及外力刺激下發(fā)生多種聚集態(tài)間的可逆轉(zhuǎn)變,從而實(shí)現(xiàn)在三種不同發(fā)光狀態(tài)間的可逆轉(zhuǎn)變.我們嘗試將化合物1用于光學(xué)記錄,以單一化合物1為發(fā)光材料,其可在藍(lán)綠及藍(lán)色熒光顏色背景上以暗黃綠色字跡記錄,可通過研磨、加熱及溶劑氣氛處理擦除字跡,并將記錄紙分別轉(zhuǎn)變?yōu)樗{(lán)色、藍(lán)綠色及黃綠色,因此化合物1有望用于光存儲(chǔ)材料.
[Abstract]:Phenyltoluenyl dibenzofurene (phenyltolyldibenzofulvene,1) was prepared and its luminescence properties were studied. Compound 1 has the properties of agglomeration induced luminescence (aggregation induced emission,AIE) and crystallization induced fluorescence enhancement (crystallization enhanced emission,CEE), and compound 1 can form blue, blue-green fluorescence crystals and the amorphous form of yellow-green fluorescence. Because compound 1 is a twisted propeller conformation, and the molecule accumulates in a looser form in the aggregate state, compound 1 can undergo reversible transformation between various aggregation states under the stimulation of heat, solvent atmosphere and external force. Thus the reversible transition between three different luminescent states is realized. We try to use compound 1 for optical recording, using a single compound 1 as a luminescent material, which can be recorded in dark yellowish green handwriting on the background of blue-green and blue fluorescent colors. It can be erased by grinding, heating and solvent treatment. The recording paper is converted to blue, blue-green and yellowish green respectively, so compound 1 is expected to be used as optical storage material.
