Novel Cu I trinuclear complexes carrying a range of alkynyl ligands with different electronic structure have been prepared. They have high quantum yields of photoluminescence. The energy, as well as the lifetime of the triplet state emission, can be tuned to a large extent by careful choice of the alkynyl ligand, making these complexes suitable candidates for application either in optoelectronic devices or in time‐resolved and gated luminescence detection. The nature of the excited state has been identified as a metal‐to‐ligand charge transfer (MLCT) state.
