Coordination polymers are attractive materials for various fields of practical application. The high degree of freedom of choice of metal ions and organic ligands plays a critical role in functional diversification. In the present study, we report the liquid-liquid interfacial synthesis of a 2D bis(terpyridine)copper(II) polymer thin film, Cu-tpy. The synthesized Cu-tpy was characterized by various microscopic observations such as TEM, SEM, and AFM, and spectroscopic measurements such as XPS, Raman spectroscopy, SEM/EDS, and UV-Vis spectroscopy. Synchrotron-radiated X-ray scattering confirmed that Cu-tpy was oriented crystalline films. Moreover, Cu-tpy showed electrochemical micro-supercapacitor behavior in the solid-state owing to its ionic nature. This study expands the potential of bis(terpyridine)metal(II) polymers as electro-functional materials.
配位聚合物是适用于各种实际应用领域的有吸引力的材料。金属离子和有机配体选择的高度自由度在功能多样化中起着关键作用。在本研究中，我们报道了二维双（三联吡啶）铜（II）聚合物薄膜Cu-tpy的液-液界面合成。通过诸如透射电子显微镜（TEM）、扫描电子显微镜（SEM）和原子力显微镜（AFM）等各种显微镜观察以及诸如X射线光电子能谱（XPS）、拉曼光谱、扫描电子显微镜/能谱仪（SEM/EDS）和紫外-可见光谱等光谱测量对合成的Cu-tpy进行了表征。同步辐射X射线散射证实Cu-tpy是取向结晶膜。此外，由于其离子性质，Cu-tpy在固态中表现出电化学微超级电容器行为。本研究扩展了双（三联吡啶）金属（II）聚合物作为电功能材料的潜力。
