| 摘 要： | 将PVK(聚乙烯基咔唑)以不同的比例掺杂至螺噁嗪光致变色化合物的体系中,通过对螺噁嗪开环体紫外-可见光谱和聚乙基咔唑荧光光谱的分析可以得出,掺杂体系中聚乙烯基咔唑中的电子空穴可容纳螺噁嗪光致变色过程中迁移的电子,从而提高了螺噁嗪开环的效率。

| Abstract: | Poly-N-vinyl-carbazole(PVK) was doped with different ratios spirooxazine.UV-Vis and fluorescence spectrum indicated that the electron holes of the PVK would accept the transporting electrons generatated by the photochromic reaction of the spirooxazine.Thus the coloration quantum yield of the photochromic reaction was improved. |
