tailored dye layers, which were employed, on one hand, for covalent deposition and, on the other hand, for non‐covalently post‐functionalizing TiO2 nanoparticle films. Our functionalization concept enabled intermixing a stable covalent attachment of a first layer with a highly versatile and reversible hydrogen bonding through the Hamilton receptor–cyanuric acid binding motif as a second layer.

我们报告了新定制的染料层,其一方面用于共价沉积,另一方面用于非共价后功能化 TiO 2纳米粒子薄膜。我们的功能化概念能够将第一层的稳定共价连接与通过汉密尔顿受体-氰尿酸结合基序作为第二层的高度通用和可逆的氢键混合。遵循这个概念,我们逐步集成了第一卟啉层和第二卟啉/BODIPY层。对各个构建块及其相应组合的光物理特性进行了探讨,最有希望的组合在染料敏化太阳能电池(DSSC)中实现。相对于第一卟啉层,添加第二卟啉/BODIPY层将总体DSSC效率提高了高达43%。
