Among various light emission phenomena, multicolour light emission, such as white light emission, is an interesting phenomenon. Bis-styrylbenzene derivatives show unique and excellent emission behaviours. In this study, three types of bis-styrene derivatives, with thiophene, pyridine, and benzene rings at the central position, were synthesised, and their photophysical properties were studied in detail. Among them, pristine crystals of ,-2,6-bis(4-cyanostyryl)pyridine (Py4CN) showed a slight bluish-white emission because the Py4CN pristine crystals were mixtures of two separate crystals emitting blue and yellow-green fluorescence.

在各种发光现象中，多色发光，如白光发射，是一种有趣的现象。双苯乙烯基苯衍生物表现出独特且优异的发光行为。在本研究中，合成了三种在中心位置带有噻吩、吡啶和苯环的双苯乙烯衍生物，并详细研究了它们的光物理性质。其中，2,6-双（4-氰基苯乙烯基）吡啶（Py4CN）的原始晶体呈现出轻微的蓝白色发射，因为Py4CN原始晶体是发射蓝色和黄绿色荧光的两种独立晶体的混合物。
