摘　　要：本文合成了含有羟基/乙基/羧基的三种螺吡喃衍生物SPOH、SPET、SPCOOH并研究了光谱性质。结果表明:三种螺吡喃的最大吸收波长和最大发射波长并没有因为端基的差异而产生明显区别;在甲醇溶液中三种螺吡喃的开环能力依次减弱(SPET>SPOH>SPCOOH);紫外光照能促进螺吡喃的开环异构。Three kinds of spiropyran derivatives containing hydroxyl group(SPOH),ethyl group(SPET),and carboxyl group(SPCOOH)were synthesized and their spectral properties were explored.The results showed that there was no essential difference in maximum absorption wavelength and maximum emission wavelength that was caused by the three groups of-OH,-C 2H 5,and-COOH.The SPET was the easiest one to open its ring in methanol followed by the SPOH while in the case of the SPCOOH its ring opening performance was the worst.It was also found that ultraviolet(UV)light irradiation can greatly promote the ring opening isomerization of the three spiropyran derivatives.
