合成了一种对称的含N-水杨醛缩苯胺(Schiff碱)单元的二芳基乙烯。通过NMR光谱、质谱和元素分析充分证实了结构。用紫外维斯吸收光谱和核磁共振谱研究了其光致变色性。结果表明,二芳基乙烯能很好地进行光异构化反应,但没有观察到明显的分子内质子转移。此外,我们还考察了金属离子对N-亚水杨基苯胺基二芳基乙烯性质的影响,结果表明Cu ~(2+)和Fe ~(3+)对二芳基乙烯开环和闭环异构体的紫外/维斯吸收光谱有显著影响。
A symmetrical diarylethene containing N-salicylideneaniline (Schiff base) units was synthesized. The structure was well confirmed by NMR spectroscopy, mass spectrometry, and elemental analysis. Its photochromism was investigated by UV/Vis absorption spectra and NMR. The result displayed that diarylethene can well perform photoisomerization, but no obvious intramolecular proton transfer was observed. Furthermore, we checked the effects of metal cations for the properties of N-salicylideneaniline-based diarylethene, which indicated that Cu2+ and Fe3+ cations can significantly affect the UV/Vis absorption spectra of diarylethene ring-open and ring-closed isomers.
