螺环光致变色材料研究进展

Research Progress of Spiro Ring Photochromic Materials

本文首先介绍了螺共轭效应的基本理论。详细叙述了一螺化合物(螺吡喃、螺噁嗪)、双螺环、偶极螺σ-体系等光致变色化合物的合成及应用方面的研究进展,并对今后的研究方向提出了建议。

The spiroconjugation effect was introcluced.The synthesis methods and application of phothchromic compounds such as nospiro compounds(spiro benzopyran,spiro benzoxazine),bis spiro compounds and bipolar spiro σ-complexes were reviewed,and the future research direction was put forward.
