摘要
本文合成了新型的含有乙酰氧基的2-苯乙烯基苯并噻唑。研究了此类化合物在固态和溶液中的荧光特性。结果表明,乙酰氧基是一种很有趣的取代基,在甲苯溶液中具有给电子特性,而在多晶粉末中由于分子间相互作用使之具有吸电子特性,导致发射谱和激发谱中的长波带蓝移。
2-styrylbenzothiazole(2-SBT) compounds with acetoxy were synthesized, and theluminescence properties of the compounds were studied in this paper. The results indicated that the acetoxy exhibits typically electronic characteristics. At toluene solution the acetoxy is donor and addition of an acetoxy in the 2-SBT molecule causes a red shift of longest excitation band and luminescence spectra because of interaction between thedonor and the acceptor in compounds Ⅱ ,Ⅲ , Ⅳ. However, at solid state the acetoxy isacceptor and the blue-shift of the luminescence spectra of 2-SBT with acetoxy in comparison with the spectra of 2-SBT due to the intramolecular hydrogenbonding.
