A new efficient synthesis of 2-styryl-6,7-dichlorothiazolo[4,5-b]quinoxaline based fluorescent dyes was achieved by the condensation of 2-methyl-6,7-dichlorothiazolo[4,5-b]quinoxaline with selected 4-N,N-dialkylaminoarylaldehydes and heteroarylaldehydes in the presence of piperidine. The coloristic, fluo-rophoric, and dyeing properties of these dyes were studied.
通过2-甲基-6,7-二氯噻唑并[4,5- b ]喹喔啉与选择的缩合反应,可以合成2-苯乙烯基-6,7-二氯噻唑并[4,5- b ]喹喔啉类荧光染料。在哌啶存在下的4- N,N-二烷基氨基芳基醛和杂芳基醛。研究了这些染料的显色,发荧光和染色性能。
