摘　　要：将冠醚结构单元与生色基团相结合所得有色冠醚可能具有某些特异性质早已引人注目。冠醚部花菁的研究曾有报道,但光致变色冠醚部花菁至今还未见报道。Five photochromic crown ether merocyanine dyes (1～5) were prepared by thecondensation of 2-methylbenzothiazolium halice, incorporating a crown ether structural com-ponent on the phenyl moiety, with substituted salicylaldehydes in the presence of piperidene.It was found that these crown ether merocyanine dyes and the corresponding spiropyran iso-mer were in reverse photochromic equilibrium where the merocyanine form is more stable thanthe spiropyran form.
