| 中文摘要: |
| 以4-甲酰基三苯胺和2-乙酰基吡啶为原料合成了配体TPAtpy，再与二价钴离子配位制备配合物Co (TPAtpy)2，最后在ITO玻璃表面采用电化学聚合制备了两种电致变色薄膜poly-TPAtpy和poly-Co (TPAtpy)2。由于Co (Ⅱ)金属离子与有机配体之间有较强的相互作用，金属配位聚合物具有更好的稳定性，poly-Co (TPAtpy)2比poly-TPAtpy表现出更好的电致变色性质，poly-Co (TPAtpy)2的光学对比度高达76.5％（750 nm），着色效率高达570.1 cm2/C，响应时间较短(着色时间：12.8 s；褪色时间1.8 s)。 |
| 英文摘要: |
| The ligand TPAtpy was synthesized from 4-formyltrianilide and 2-acetyl pyridine, which was subsequently coordinated with cobalt bivalent ion to obtain the complex Co(TPAtpy)2. Finally, two novel electrochromic materials poly-TPAtpy and poly-Co(TPAtpy)2 were deposited on ITO substrates by electrochemical polymerization. Due to the strong interaction between Co(Ⅱ) ion and terpyridine-based ligands, the corresponding coordination polymer showed better stability. Compared with poly-TPAtpy, poly-Co(TPAtpy)2 exhibited superior electrochromic performance, involving large optical contrast up to 76.5% at 750 nm and high coloration efficiency over 570 cm2/C, as well as fast switching speed (the coloration time was 12.8 s and the bleaching time was 1.8 s, respectively). |
