conjugation length and substituents with different electron-donating or accepting abilities in the triphenylethylene skeleton. The density functional theory calculations further demonstrated that with the increase of the electron-donating or accepting abilities of the substituents, the energy gaps of the fluorophores gradually decreased, which elucidated the substituent effect of the organic fluorophores
高效合成了一系列基于三苯乙烯的发光分子。然后研究了荧光团对其光物理性质的取代作用。因此,发现更长的共轭体系和更大的供体-π-受体荧光团分子偶极子可能导致紫外可见吸收和发射谱带的红移,斯托克斯位移也是如此。特别是,通过改变共轭长度和三苯基乙烯骨架中具有不同供电子或接受能力的取代基,可以实现溶液和固态的全色荧光发射。密度泛函理论计算进一步表明,随着取代基的供电子或受电子能力的增加,
