Photoactive <i>N</i> ‐heterocyclic carbene transition metal complexes in bond‐forming photocatalysis: State‐of‐the‐art and opportunities

This Minireview presents and discusses recent developments in photoactive/photoluminescent N-heterocyclic carbene (NHC) transition metal complexes their viability as catalysts bond-forming photocatalysis. Specifically, we summarise key structural motifs adopted by photoactive NHC highlight some of photophysical properties. Representative examples applications photochemical reactions are also showcased presenting the state-of-the-art future opportunities for this exciting class complexes.
