Abstract Synthesis and structural characterization of peripherally polar substituent zinc phthalocyanine, based on extended π -conjugation concept, were carried out for efficient far-red/near-IR performance in nanocrystalline TiO 2 films. The new compounds were characterized using FTIR, UV–Vis, fluorescence spectroscopies, 1 H NMR, cyclic voltammetry, differential pulse voltammetry and elemental analysis
摘要 基于扩展的π-共轭概念,进行了周边极性取代基酞菁锌的合成和结构表征,以提高纳米晶TiO 2 薄膜的远红/近红外性能。使用 FTIR、UV-Vis、荧光光谱、 1 H NMR、循环伏安法、微分脉冲伏安法和元素分析对新化合物进行了表征。从还原和氧化行为,证明PPC和QPC具有负LUMO能级和正HOMO能级,满足能隙规则,PPC和QPC可用作DSSC应用的敏化剂。
