Novel photochromic 5′-(1,3-benzothiazol-2-yl)-substituted spiro[indoline-2,3′-naphthopyrans] possessing luminescence properties in both the cyclic and merocyanine forms were synthesized. Unlike the 8′-(1,3-benzothiazol-2-yl)-substituted benzopyran analogs, the synthesized compounds are characterized by the lower relative stability of the merocyanine isomers.
合成了新型光致变色的 5′-(1,3-苯并噻唑-2-基)取代螺[吲哚啉-2,3′-萘并吡喃],其环状和经花青素形式均具有发光特性。与 8′-(1,3-苯并噻唑-2-基)取代的苯并吡喃类似物不同,所合成的化合物的特点是经花青素异构体的相对稳定性较低。
