[Ru(bpy)<sub>3</sub>]<sup>2+</sup> Derivatives-Incorporated POM@MOFs with Good Photocatalytic Activity for Visible-Light-Driven Oxidative Coupling of Amines to Imines
Two novel POM@MOFs, {H<sub>3</sub>Zn<sub>2.5</sub>(H<sub>2</sub>O)<sub>10</sub>[Ru(dcbpy)<sub>3</sub>][PMo<sub>11</sub><sup>VI</sup>Mo<sup>V</sup>O<sub>40</sub>]}·2H<sub>2</sub>O (<b>RuZn-PMo</b>) and {H<sub>3</sub>Ni<sub>2.5</sub>(H<sub>2</sub>O)<sub>12</sub>[Ru(dcbpy)<sub>3</sub>][PMo<sub>11</sub><sup>VI</sup>Mo<sup>V</sup>O<sub>40</sub>]}·5H<sub>2</sub>O (<b>RuNi-PMo</b>), have been synthesized through a traditional hydrothermal method. They are composed of [Ru(bpy)<sub>3</sub>]<sup>2+</sup>-derived hexa-carboxylate and Keggin-type anion [PMo<sub>11</sub><sup>VI</sup>Mo<sup>V</sup>O<sub>40</sub>]<sup>4-</sup>. In addition, their structures were well characterized by various spectroscopic methods. Under the irradiation of visible light (λ > 400 nm), <b>RuZn-PMo</b> and <b>RuNi-PMo</b> as heterogeneous photocatalysts showed efficient photocatalytic performance in the coupling reaction of amines, with TONs of 451 and 454, respectively. Moreover, <b>RuZn-PMo</b> exhibited excellent reusability and stability after three continuous reaction cycles. Besides, EPR measurements were performed to elucidate the reaction mechanism.
