摘要： 取代的吲哚啉螺苯并吡喃具有光致变色性质,在光信息显示和记录等现代技术领域已取得初步应用。以往的工作表明,这类化合物的光致变色性质与分子中的取代基有密切关系。氮上有长链烷基的吲哚啉螺苯并吡喃已有报道。

Abstract: The title compounds(Ⅲa, R1=H, R2=NO2, Ⅲb, R1=NO2,R2=H, Ⅲc,R1=Cl,R2=NO2,Ⅲb, R1=Br,R2=NO2, Ⅲc, R1=R2=NO2) were prepared by condensation of 1-octyl-3,3-dimethyl-2-methyleneindoline (Ⅰ) and substituted salicylaldehydes (Ⅱ) in anhydrous ethanol. Photochromic properties of these compounds were investigated by UV/VIS spectra measurement and photochromic film obtained from Ⅲa-c Compounds Ⅲa and Ⅲc-e are found to be good photochromic reagents.
