利用Wittig反应将高荧光量子产率的蒽基团通过双键连接在四硫富瓦烯单元上,合成了二元共轭体系化合物TTFan.在氧化作用的控制下,四硫富瓦烯单元的给电子能力降低,TTFan的荧光发射强度增大至原来的十几倍,实现了荧光的“off-on”过程.
The Wittig reaction was used to couple the high fluorescence quantum yield anthracene group to tetrathiafulvalene via double bond to synthesize the binary conjugate system TTFan. Under the control of oxidation, the tetrathiafulvalene To reduce the electronic capabilities, TTFan fluorescence emission intensity increased to ten times the original, to achieve the fluorescence of the “off-on” process.
