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

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.
