以甲醇作溶剂,在六氢吡啶存在下使5.5’—甲撑双水杨醛与吲哚啉碘化物反应制得七种双吲哚啉螺苯并吡喃(Ⅲ_(a-g))。测定了它们的红外和紫外—可见光谱。并对这些化合物的光致变色性质进行了初步的考察。
Seven bisindoline spirobenzopyrans (Ⅲ_ (a-g)) were prepared by the reaction of 5.5’-methyldisalicylaldehyde with indoline iodide in the presence of hexahydropyridine using methanol as the solvent. Their infrared and UV-Vis spectra were measured. The photochromic properties of these compounds were also investigated.
