Three photoactive Cd(II) coordination polymers (CPs), [Cd (Fsbpe)(DBBA)]·2DMF (CP), [Cd(Fepbpe)(DBBA)]·2DMF (CP) and [Cd(Fsbpeb)(DBBA)] (CP) (DBBA = 3,5-dibromobenzoic acid, DMF = dimethyl formamide) with similar 1D chain motifs exhibited completely different photosalient behaviors (PS) in response to UV light. Mechanical motion was triggered by [2+2] photocycloaddition and regulated by positioning of the photoactive alkene centers relative to the crystal axis. This solid-state reaction was reversed by heating and photomechanical behaviour was repeated over several cycles. A simple photoactuating device was prepared using a CP3-PVA composite.
三种具有相似一维链状结构的光活性镉（II）配位聚合物（CPs），即[Cd (Fsbpe)(DBBA)]·2DMF（CP）、[Cd(Fepbpe)(DBBA)]·2DMF（CP）和[Cd(Fsbpeb)(DBBA)]（CP）（DBBA = 3,5-二溴苯甲酸，DMF = 二甲基甲酰胺），在紫外光照射下表现出完全不同的光致突变行为（PS）。机械运动由[2+2]光环化加成引发，并受光活性烯烃中心相对于晶轴的位置调节。这种固态反应通过加热逆转，光机械行为可在几个循环中重复。使用CP3-PVA复合材料制备了一种简单的光驱动装置。
