取代螺吡喃类化合物的合成及其光致变色性能

Synthesis and photochromism of substituted spiropyran compounds

选取了具有代表性的取代基合成了带有不同取代基的系列螺吡喃类化合物,并对这些化合物进行了光响应研究以及动力学实验,考察其对光致变色性能的影响,以期发现取代基对该光致变色化合物的影响规律。结果表明:苯并吡喃环侧引入吸电子基且在二氢吲哚侧引入供电子基,所制化合物表现出优异的光致变色性能。

Typical substituents were selected to synthesize a series of spiropyran compounds with different substituents. The light response and dynamic experiments were conducted to observe the photochromic property of the compounds and determine the contribution of substituents to the compounds. The results show that electron-acceptor groups are introduced to the ring side of benzopyran and electron-donor groups to the side of indoline, making the compounds produced perform excellently in photochromism.
