Cyclometalated luminescent platinum(II) complexes of dissymmetrical 2,2':4',2"--terpyridine and its self--assembled dimer presenting Pt--Ag dative bonds
Résumé
A series of cyclometalated (N^C^N) Pt(II)--platinum complexes featuring a terpyridine ligand with a non--coordinating nitrogen atom and a Pt--C bond was synthesized. In the presence of Ag + , the bis(isonitrile)Pt(II) complex formed a remarkable self--assembled helicoidal dimer stabilized by coordination of Ag(I) and metallophilic Pt--Ag interactions.
Its assembly was observed in the solid state and maintained in solution. All complexes show strong luminescence and multiple emitting states, which could be rationalized based on solid state X--ray structures and coordinating environment.
