Anchoring Ir(III) complex on macroscopic polymer substrate as highly durable photosensitizer for photocatalytic hydrogen evolution.

A novel photosensitizer (PS) was developed by anchoring an Ir(III) complex on a macroscopic polymer substrate to prevent ligand dissociation of the PS, resulting in a long duration of over 730 h in photocatalytic hydrogen evolution. This study paves the way for designing new Ir(III) PSs and exploring the inactivation mechanism of PSs. [ABSTRACT FROM AUTHOR]
