Topological Insulator‐Supported Organic π ‐Dimers Enable Heterogeneous conPET Photocatalysis for Inert C–X Bond Functionalization
The photocatalytic activation of inert aryl halides remains a central challenge in organic synthesis due to their high reduction potentials and limited accessibility by conventional visible‐light photocatalysts. Herein, we report a heterogeneous photoredox system based on a topological insulator‐supported organic...
