In this study, a new type of functional, self‐assembled nanostructure formed from porphyrins and polyamidoamine dendrimers based on hydrogen bonding in an aqueous solution is presented. As the aggregates formed are promising candidates for solar‐energy conversion, their photocatalytic activity is tested using the model reaction of methyl viologen reduction. The self‐assembled structures show significantly increased activity as compared to unassociated porphyrins. Details of interaction forces driving the supramolecular structure formation and regulating catalytic efficiency are fundamentally discussed.

水中的氢键聚合物-卟啉组装体：用于光能转化的超分子结构

在这项研究中，提出了一种新型的功能性，自组装的纳米结构，其由卟啉和聚酰胺基胺树枝状聚合物基于水溶液中的氢键形成。由于形成的聚集体是太阳能转化的有希望的候选者，因此使用甲基紫精还原的模型反应测试了它们的光催化活性。与未结合的卟啉相比，自组装结构显示出显着增加的活性。从根本上讨论了驱动超分子结构形成和调节催化效率的相互作用力的细节。
