摘要：
Several new delocalized cationic azo dyes incorporating a bathochromic thiazole moiety have been prepared in moderate to good yields. The synthesis involved the Knoevenagel condensation of an intermediate azo Compound, hearing a terminal formyl group, with methylenic bases generated in situ from benzoazolium and quinolinium salts. All dyes display strong absorption around 700 nut and have shown negative solvatochromic behaviour. (c) 2007 Elsevier Ltd. All rights reserved.
