作者用含冠醚结构单元的2-甲基-苯并噻唑季铵盐与取代水物醛缩合得到了五个光致变色冠醚部化菁化合物。这些新的冠醚化合物具有逆光致变色性质, 较稳定的结构是开环部花菁式。

Five photochromic crown ether merocyanine dyes were prepared by the condensation of 2-methylbenzothiazolium halide incorporating a crown ether structural component on the Ph moiety, with substituted salicylaldehydes in the presence of piperidine. These crown ether merocyanine dyes and the corresponding spiropyran isomer were in reverse photochromic equilibrium where the merocyanine form is more stable than the spiropyran form.
