A powerful and attractive route to develop novel photocatalysts for C–N bond formation involves the use of pyrrolidine as the substrate and cocatalyst simultaneously. Herein, a new polyoxometalate (POM)-based metal–organic framework, namely, [Ni6(OH)3(H2O)9(DPNDIH)(SiW9O34)]2·2H2O (SiW9Ni6-DPNDI) (DPNDI = N,N′-di(4-pyridyl)-1,4,5,8-naphthalenediimide), was prepared by incorporating a Ni6 cluster-substituted POM anion and a photosensitizer (DPNDI) into a framework. The anion···π interactions and covalent bonds between SiW9Ni6 and DPNDI are beneficial for the consecutive electron separation and transfer. Under visible-light irradiation, DPNDI can be easily excited to generate radical species DPNDI* that could be further excited in the presence of the electron donor pyrrolidine for the inert O2 activation. SiW9Ni6-DPNDI showed a high efficiency in the photocatalysis of C–N bond formation under a mild condition by the synergy of DPNDI and SiW9Ni6. The results of the reaction were confirmed by gas chromatography and 1H NMR. In addition, SiW9Ni6-DPNDI exhibited a high sustainability without an obvious change in yields after five cycles.
