合成了一种新型“A‐D‐A”型有机配体L（其中，A为三联吡啶、D为取代芴基）及其金属钯齐聚物（（L2 Pd）n ），对其结构进行了红外光谱和核磁图谱表征。将该芴‐三联吡啶钯齐聚物作为活性层制备制得固态电致变色器件（结构为 ITO／（L2 Pd）n／PE ∶ Li‐ClO4‐PMMA‐PC／ITO），对该器件施加0～24． V的偏压时器件的颜色由深黄色变为橘红色，在未封装条件下其变色态稳定时间可达1h；当施加反向电压时器件颜色可由橘红色回复至深黄色。
A novel“A‐D‐A” organic ligand L (A :terpyridine;D :fluorenyl) and its palladium complex (L2 Pd)n were synthesized and their structures were characterized by 1 H NMR and IR spectra .A solid electrochromic de‐vice (ECD) with fluorenyl‐terpyridine‐palladium complex (L2 Pd)n as active layer was prepared in the structure of “ITO/(L2 Pd)n/PE∶ LiClO4‐PMMA‐PC/ITO” .Color of this device (ECD) was reversiblely changed from yellow to orange under the change of voltage from 0 to 2 4. V ,which can maintain more than 1 h without encap‐sulation .
