The covalent attachment of molecular photosensitizers (PS) to polyoxometalates (POMs) opens new pathways to PS-POM dyads for light-driven charge-transfer and charge-storage. Here, we report a synthetic route for the covalent linkage of BODIPY-dyes to Anderson-type polyoxomolybdates by using CLICK chemistry (i. e. copper-catalyzed azide-alkyne cycloaddition, CuAAC). Photophysical properties of the dyad were investigated by combined experimental and theoretical methods and highlight the role of both sub-components for the charge-separation properties. The study demonstrates how CLICK chemistry can be used for the versatile linkage of organic functional units to molecular metal oxide clusters.
分子光增敏剂（PS）与多金属氧酸盐（POM）的共价连接为光驱动电荷转移和电荷存储开辟了 PS-POM 偶联物的新途径。在这里，我们报告了一种通过使用点击化学（即铜催化的叠氮化物-炔烃环加成反应，CuAAC）将 BODIPY 染料共价连接到安德森型多金属氧酸盐的合成途径。通过组合实验和理论方法研究了偶联物的光物理性质，突出了两个亚组分在电荷分离性质中的作用。该研究展示了点击化学如何用于将有机功能单元与分子金属氧化物簇灵活连接。
