摘要：采用对甲苯磺酸催化合成N^1-烷基-1,2,3-三氮唑和N^2-烷基-1,2,3-三氮唑。两种产物均有紫外吸收,但只有N^2-烷基-1,2,3-三氮唑有荧光。研究了在N^2位和C^4位引入不同取代基后化合物的紫外可见吸收光谱和荧光激发发射光谱。结果表明,N^2位是甲苯基或C^4位是吸电子取代基的荧光强度最高,荧光量子产率高达79%,调节C^4位取代基可以更好地提升荧光性能(荧光发射波长300~440 nm,Stokes位移49~70 nm)。N^2-烷基-1,2,3-三氮唑良好的蓝紫光荧光性能使其具有潜在应用价值。
N 1-alkyl-1,2,3-triazoles and N 2-alkyl-1,2,3-triazoles were prepared,and their photophysical properties were investigated.Both type of 1,2,3-triazoles have strong photo absorptions at near 250 nm,however only N 2-alkyl-1,2,3-triazoles give fluorescence emissions.From the screen of the photophysical properties of different substituted N 2-alkyl-1,2,3-triazoles at N 2-or C 4-sites,it is found that N 2-alkyl-1,2,3-triazoles bearing rich electron benzyl group at N 2-site or poor electron phenyl group in C 4-site have the strong fluorescent intensity,and the quantum yields are up to 79%with 300-440 nm of fluorescent emissions and 49-70 nm of Stokes shifts.The photophysical properties of N 2-alkyl-1,2,3-triazoles show their potent application in the development of fluorescent materieals.
