| 摘要: 在溶剂热合成条件下，将紫精配体1，1′-二(3-羧基苯基)-(4，4′-联吡啶)二氯化物(H2bcbpy·2Cl)和KI与金属镉离子配位，成功构筑了一例紫精基热致变色配位聚合物[Cd(bcbpy) I2]·2H2O (1)，该配合物为一维链状结构且具有热致变色性能。在不同温度刺激下，该配合物由绿色缓慢转变为黄绿色，随着温度的升高，配合物1的颜色逐渐加深，最后变为橘黄色。因此，我们将配合物1制作成了感温变色薄膜。此外，我们还对配合物1进行了电化学测试，结果表明该配合物为半导体材料。 | |

| Abstract: Under the condition of solvothermal synthesis, the viologen ligand 1,1′-bis(3-carboxyphenyl)-(4,4′-bipyridine) dichloride (H2bcbpy·2Cl) and KI are coordinated with the metal cadmium ions. A case of thermochromic coordination polymer [Cd(bcbpy) I2] ·2H2O (1) was constructed. Complex 1 displays a 1D chain structure and exhibits thermochromic behavior. Under different temperature stimulation, the complex slowly changed from green to yellowgreen, and with the increase of temperature, the color of complex 1 gradually deepened, and finally became orangeyellow. Therefore, complex 1 was prepared as a thermochromic film. In addition, we also performed electrochemical tests on complex 1, which showed that the complex is a semiconductor material. | |
