Iridium-based Metallo-organic Triangles as Efficient Photosensitizers for Rhodamine B Photocatalytic Oxidation Degradation

Abstract

In this study, two metallo-organic triangular architectures (S1 and S2) based on the Iridium(III) complex were successfully constructed. Electron paramagnetic resonance (EPR) analysis confirmed that S1 and S2 can efficiently generate reactive oxygen species (ROS) under light irradiation. In photocatalytic degradation experiments, both triangles exhibited outstanding performance toward Rhodamine B (RhB). Specifically, S1 and S2 achieved degradation rates of 82.5% and 84.9% within 10 minutes, respectively. This work highlights the great potential of Iridium-based supramolecular architectures in rapid and efficient photodegradation of organic pollutants.
