A series of luminescent pincer-type cyclometalated platinum(II) complexes, namely [4-R-(N∧C∧N)PtCN(C6H3-2,6-Me2)]PF6 (2–4; 4-R-(N∧CH∧N) represents substituted 1,3-bis(2′-pyridyl)benzene ligands), were prepared under phase-transfer conditions. Complex 2 shows two solvatomorphic crystal structures and exhibits vapoluminescent response toward acetonitrile vapor. The photophysical properties of and supramolecular nanowires formed from these complexes were also investigated.
