We present a simple and effective way of using metal and metal-ligand modifications to tune the electrochemical and optical properties of conducting polymers. To that end, a polyterthiophene functionalized with terpyridine moieties was synthesized and then the resulting film's surface or bulk was modified with different metal ions, namely Fe, Zn and Cu and terpyridine. The modification of the terpyridine functionalized polyterthiophene film by Fe increased the absorptivity and electrochemical capacitance of the conducting polymer, and improved its conjugation. Further modification by Zn and Cu resulted in dramatically different spectroelectrochemical properties of the film. Moreover, the influence of the solvents (ACN and 1 : 1 ACN : HO) in conjunction with the metal ion applied for the modification was found crucial for the electrochemical and optical properties of the films.
我们提出了一种利用金属和金属-配体修饰来调节导电聚合物的电化学和光学性质的简单有效方法。为此，合成了一种用三联吡啶部分官能化的聚噻吩，然后用不同的金属离子（即铁、锌和铜）以及三联吡啶对所得薄膜的表面或本体进行修饰。铁对三联吡啶官能化聚噻吩薄膜的修饰提高了导电聚合物的吸收率和电化学电容，并改善了其共轭性。锌和铜的进一步修饰导致薄膜的光谱电化学性质有显著不同。此外，发现溶剂（乙腈和1:1乙腈:水）与用于修饰的金属离子相结合对薄膜的电化学和光学性质至关重要。
