dinuclear metal terpyridine (M-tpy; M = Ru, Os, Fe, and Co) complexes with a photochromicdithienylethene bridge were designed and synthesized through either a convergent or a divergent approach. The open forms of the complexes containing RuII and FeII centers were found to be inert to ultraviolet photoirradiation but could be cyclized electrochemically as revealed by a cyclic voltammetric study. On the contrary
设计了一系列具有光致变色二噻吩乙烯桥联的双核金属联吡啶(M-tpy; M = Ru,Os,Fe和Co)配合物,并通过收敛或发散方法进行了合成。发现包含RuII和FeII中心的复合物的开放形式对紫外光辐照是惰性的,但可以通过循环伏安法研究显示其可以电化学方式环化。相反,CoII配合物进行了有效的光化学反应,但未进行电化学环化。相应的OsII复合物既不是光致变色的也不是电致变色的。

Abstract Some europium-based dithienylethenes have been synthesized and their structures have been confirmed by IR spectroscopy and elemental analysis. The photochromic properties and luminescent behaviors of these compounds in solution have been measured upon irradiation with UV or visible light. UV/vis absorption and luminescence spectra indicated that these dithienylethenes displayed obvious photochromism
