The use of azide-alkyne cycloaddition (“click chemistry”), both Cu-catalysed and Cu-free, was probed to attach different porphyrins onto oligodeoxynucleotides (ODNs), and the efficiency was compared to amide coupling reaction. Terminal attachment using the different methodologies provides porphyrin-ODNs in varying yields, and the porphyrin-ODNs can be transformed into multiporphyrin arrays using DNA-templated assembly. These arrays show exciton coupling between the porphyrin units and thus demonstrate an efficient and alternative route to multiporphyrin assemblies.

用卟啉进行合成后 DNA 修饰，用于 DNA 模板超分子组装

探索使用叠氮-炔环加成（“点击化学”）（铜催化和无铜）将不同的卟啉附着到寡脱氧核苷酸（ODN）上，并将效率与酰胺偶联反应进行比较。使用不同的方法进行末端连接可提供不同产量的卟啉-ODN，并且可以使用 DNA 模板组装将卟啉-ODN 转化为多卟啉阵列。这些阵列显示了卟啉单元之间的激子耦合，从而证明了多卟啉组装的有效且替代的途径。
