为了获得相容性好的农膜转光剂,以乙腈、乙醇和糠醛为原料,合成了2,4,6-三(α-呋喃乙烯基)-1,3,5-均三嗪(TFT),通过元素分析、傅里叶变换红外光谱仪、紫外-可见分光光度计和核磁共振氢谱仪对TFT进行了表征。结果表明:TFT氯仿溶液在波长375nm的紫外光激发下,发出440nm左右的蓝紫光;固体TFT在波长378nm的紫外光激发下,发出450～550nm的蓝光,与植物光合作用需要的蓝紫光(400～480nm)相匹配;固体TFT的发射光强度比TFT在氯仿溶剂中强很多,且发射峰红移近40nm,这种现象可能是固体TFT具有聚集诱导发光效应,有利于其应用于转光农膜。
In order to obtain good compatibility agriculture film,2,4,6-thris (α-furyl ethenyl)-1,3,5-s-triazine(TFT) was synthesized with acetonitrile,alcohol and furfural,and characterized by element analysis,FT-IR spectrum,UV spectrum and 1H-NMR.TFT in chloroform solution emitted about 440nm blue violet light when excited at 375nm violet light.The solid TFT emitted 450～550nm blue light excited at 378nm violet light,red shift 40nm or so,and more stronger than that of TFT solution.The phenomenon could be explained by agglomeration induced luminescence effect of TFT and fitted for light-conversion agriculture film.
