  摘要：

  A series of dimethyl 6-aryl-2,2dimethyl-2N-chromene-7,8-dicarboxylates were synthesized, and the photochromic properties of this new family of dimethyl-2H-chromenes were studied under continuous irradiation. The presence of the methoxycarbonyl groups was shown to stabilize the colored forms. This stabilization depended on the solvent, and in two cases the formation of long-lived opened forms was observed. Under irradiation with a mercury lamp, this family of 2H-chromenes showed a strong resistance: to photodegradation.

  Synthesis and Spectrokinetic Studies of a New Family of Dimethyl [2H]-Chromenes: Dimethyl 6-Aryl-2,2Dimethyl-[2H]-Chromene-7,8-Dicarboxylates

  摘要：

  The synthesis of a series of dimethyl 6-aryl-2,2-dimethyl-[2H]-chromene-7,8-dicarboxylates is described. The photochromic properties of this new family of dimethyl-[2H]-chromenes have been studied in solution, under continuous irradiation. The presence of the methoxycarbonyl groups was shown to stabilise the coloured forms. The fading rates are generally low in comparison with the standard "naked" chromenes in the same experimental conditions. This stabilisation depends on the solvent used. We could observe the presence of one permanent opened form. Moreover, it seems that the synthesised molecules have a strong resistance toward photodegradation.
