“…As part of our ongoing study on the coordination behavior of a hydrophilic sulfur-containing amino acid in the presence of a hydrophobic coligand, − we synthesized simple, mononuclear palladium(II) and platinum(II) complexes with mixed 1,3-bis(diphenylphosphino)propane (dppp) and l -cysteinate ( l -cys), namely, [M(dppp)( l -cys)] (M = Pd II , Pt II ). Whereas these complexes are not emissive in the hydrate form, strong yellow emission is observed in the presence of methanol molecules of crystallization.…”

The selective detection of methanol by photoluminescence under environmental conditions has been a great challenge for materials science. Herein, a reversible, turn-on-type photoluminescence triggered by methanol vapor in square-planar palladium(II) and platinum(II) complexes, newly prepared from [MCl2(1,3-bis(diphenylphosphino)propane)] and L-cysteine, is reported. Both the "turn-on" and "turn-off" states of the complexes were crystallographically characterized, which revealed the presence of intermolecular OH···O and CH···π interactions between methanol and the complex molecules in the turn-on state. These interactions prevent the vibrational quenching of the luminescence, leading to the turn-on-type luminescence in this system.
