两个色烯类有机光致变色体的结构分析

Structural Analyses of Two Photochromic Compounds with Chromene Skeleton

色烯类有机物是有广泛应用价值的有机光致变色体,文章探讨两个结构和性质高度相似的色烯变色体的结构解析.两个单体化合物的核磁共振(NMR)实验得到两个化合物的一维和二维NMR谱图和实验数据,两个化合物的质谱(MS)实验获得化合物的分子量,两个化合物的NMR和MS实验数据分析鉴定了两个化合物的分子平面结构.两个化合物均为2位二苯取代茚骈和苯骈色烯类的有机光致变色体.

Chromene derivatives are organic photochromic substance with wide application value.The molecular structures of two organic compounds,with very similar structure and properties,are analyzed by 1D-and 2D-NMR.And molecular weights of the two compounds was obtained by mass spectrometry(MS)analysis.They are photochromic compounds of indeno-and benzochromene derivatives substituted by 2-dipheny.
