A novel efficient synthesis of 2-styrylthiazolo[4,5-b]quinoxalinebasedfluorescentdyes was achieved by the condensation of 2-alkylthiazolo[4,5-b]quinoxaline with selected 4-N,N-dialkylamino-substituted aryl-aldehydes or hetarylaldehydes in the presence of piperidine or acid anhydride. The coloristic, fluorophoric and dyeing properties of these dyes were studied.
通过2-烷基噻唑并[4,5- b ]喹喔啉与选定的4 - N,N-二烷基氨基取代的芳基醛的缩合反应,实现了2-苯乙烯基噻唑并[4,5- b ]喹喔啉类荧光染料的新型高效合成。或在哌啶或酸酐存在下的杂芳基醛。研究了这些染料的着色,荧光和染色性能。
