Structural Optimization of Supported Organic Photocatalyst

The successful realization of a photoredox catalyst play in important role in the photocatalyzed transformation especially if the design of the photocatalyst give the chance to achieved different redox potential of the exited state. We are started from a well know TADF photocatalyst, the 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN), as a reference, e we have apported electronic optimization modifying the donors groups, using substituted carbazoles and diphenylamines. Adding to this, an important goal is obtained creating an easy recoverable system in which the photocatalyst is supported. To do this, we have functionalized the photocatalyst with a group capable to polymerized with the objective to have a SI-ARGET ATRP from silica particles. Finally, we demonstrate that the photocatalyst-functionalized can be efficient in photocatalyzed reaction.
