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 E,E-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,例如白光发光,是一种有趣的现象。双苯乙烯基苯衍生物表现出独特而优异的排放行为。本研究合成了中心位置为噻吩、吡啶和苯环的三种双苯乙烯衍生物,并对其光物理性质进行了详细研究。其中,E , E -2,6-bis(4-cyanostyryl)pyridine (Py4CN) 的原始晶体显示出轻微的蓝白色发射,因为 Py4CN 原始晶体是两种独立晶体的混合物,发出蓝色和黄绿色荧光。
