摘要
光致变色材料具有明显的光学活性,在特定波长的光的照射激发下,其颜色会随材料分子结构的异构化而发生可逆的变化。为了开发新型的光致变色材料,国内外学者在林产品和其他材料的改性上做了大量的研究工作,并取得了许多的研究成果。本文阐述了螺吡喃类、偶氮苯类、二芳基乙烯类和水杨醛席夫碱类等目前研究较多的4种有机光致变色化合物及其在材料改性上的应用;在探讨有机光致变色化合物光致变色机理、分析有机光致变色化合物研究现状的基础上,展望了有机光致变色化合物在生物质材料改性中的研究前景。
Photochromic material has obvious optical activity.Under the irradiation and excitation of specific wavelength of light,its color will change reversibly with the isomerization of the molecular structure of the material.In order to develop new photochromic materials,domestic and foreign scholars have make a lot of researches on the chemical modification of biomass materials and other materials and obtain a plenty of research achievements.In this paper,spiropyranes,azobenzenes,diaryl ethylenes and salicylaldehyde schiff bases and other organic photochromic compounds which have been widely studied and their applications in material modification were described.On the basis of discussing the photochromic mechanisms of organic photochromic compounds and analyzing the research status of organic photochromic compounds,the research potentials of organic photochromic compounds in biomass material modification was prospected.
