The Solid‐State Emission of AIPE‐Active Tricarbonylrhenium(I) Complexes Shifts to the Red: The Unexpected Performance of Triphenylphosphine Derivatives

Aggregate, Volume 7, Issue 7, July 2026.
New phosphino tricarbonylrhenium(I) complexes have efficient red emission in the aggregate and solid states. The good photostability and the vast possibilities of chemical modifications make these Re‐based complexes the starting point of a new generation of red emitters with aggregation‐induced phosphorescence emission (AIPE) characteristics.
