Recyclable, Immobilized Transition‐Metal Photocatalysts

The use of transition-metal complexes as photocatalysts have allowed the performance diverse organic transformations in an outstanding manner, characterized not only by high yields, TOF, and selectivity values, but also modulating providing access to novel molecular structures that, without them, would be difficult if impossible. However, one biggest concerns regarding these relies on difficulties associated with their isolation from reaction media reutilization once chemical process ends. above, besides contaminating products requiring out tedious purification processes, prompts inevitable loss catalyst, directly affecting its recyclability. In addition, this situation results negative outcomes economic environmental perspective, since are usually expensive materials, unsuccessful recovery could result leakage into environment. These drawbacks served inspiration for elaboration present review focused development strategies developed during last decade successful species. summarized herein, whether homogeneous or heterogeneous systems, based thermotropic solvents, changes hydrophilic balance employment polymers, copolymers, porous macromolecular structures, inorganic nanostructures support entities. Moreover, organized confining media, such micelles gels context, is discussed. We hope that will motivate search new develop catalytic understanding yields recyclability, sustainability, responsibility
