geometry simulation, by using the Gaussian 09 program. In terms of fluorescence properties in this series, two dyes based on diphenyl sulfonyl and three dyes based on triphenylamine substituted by 1–3 of N-n-butyl-carbazole exhibited a blue emission, whereas three dyes based on triphenylamine substituted by 1–3 of N-n-butyl-naphthalimide were observed by a red emitter which can be attributable to both effects
在这项研究中,基于三种不同类型的中心部分(例如三苯胺,二苯砜或三苯基三嗪)制备了十种荧光染料,它们通过乙炔键连接到咔唑或萘二甲酰亚胺基上。ñ - Ñ丁基咔唑,ñ -苯基咔唑或ñ - ñ丁基萘二甲酰亚胺偶联到三苯胺的各个中央部分,二苯基砜,2,4,6-三苯基-1,3,5-川芎嗪或在最后一步中使用Sonogashira偶联反应合成二苯胺。通过1确认所有染料的化学结构1 H NMR,GC-质谱和元素分析。检查了荧光染料的吸收特性和热稳定性。除几何模拟外,还使用高斯09程序进行了密度泛函理论(DFT)和时变DFT计算。在本系列荧光特性方面,两种染料基于二苯基磺酰基和基于由三苯胺的1-3个所取代三种染料ñ - ñ丁基咔唑表现出发蓝色荧光,而基于三苯胺三种染料被1-3取代的的N - n通过红色发射体观察到了丁基丁基萘二甲酰亚胺,这既可归因于吸收最大值的红移,也可归因于较大的斯托克斯位移。在相应的2,4
