Diarylethene-containing ligands and their coordination compounds are described. The ligands display photochromism with UV excitation, while the coordination compounds display photochromism with both excitation in the UV region and excitation into lower energy absorption bands characteristic of the coordination compounds, through which the excitation wavelengths for the photocyclization can be extended from lambda <= 340 nm to wavelengths beyond 470 nm. Switching of the luminescence properties of the compounds has also been achieved through photochromic reactions.
描述了含二芳基
乙烯基配体及其配位化合物。这些
配体在紫外激发下显示光致变色性质,而配位化合物则在紫外区域激发和激发到特征于配位化合物的较低能量吸收带中显示光致变色性质,通过这些激发波长,光环化的激发波长可以从λ <= 340 nm延伸到超过470 nm的波长。通过光致反应也实现了化合物的发光性质的切换。
