pyrimidine ring of dyes and the Lewis acid sites (exposed Tin+ cations) of the TiO2 surface. This work demonstrates that the pyrimidine rings of dye sensitizers that form a coordinate bond with the Lewis acid site of a TiO2 surface are promising candidates as the electron-withdrawing anchoring group. The data from quantum calculations show that all of the dyes are potentially good photosensitizers for dye-sensitized
通过微波辅助的Suzuki交叉偶联和氢反应的亲核芳族取代相结合,以高收率获得了六种以嘧啶为锚定基团的新型供体-π-受体有机染料。对其吸收,光致发光和电化学性质进行了详细的研究。吸附在TiO 2上的染料的红外光谱表明,在染料的嘧啶环与TiO 2表面的路易斯酸位点(暴露的Ti n +阳离子)之间形成了配位键。这项工作表明染料敏化剂的嘧啶环与TiO 2的路易斯酸位点形成配位键表面是有希望的候选物作为吸电子锚定基团。来自量子计算的数据表明,对于染料敏化太阳能电池,所有染料都是潜在的良好光敏剂。
