Abstract

The reaction of sodium salt of poly-l-glutamic acid (P(Glu)) with didodecyldimethylammonium (DDA) bromide was demonstrated to afford P(Glu)-DDA, which was confirmed to form the α-helical structure even in methanol. The introduction of 0.2 equiv. amount of the platinum(II) complex [Pt(trpy)C ≡ CPhC12H25-p](OTf) (trpy = 2,2′,6′,2″-terpyridine; PtC12) into P(Glu)-DDA in methanol was found to induce the aggregation of platinum(II) complexes, resulting in the exhibition of the triplet metal-metal-to-ligand charge transfer emission. Such synergistic effect was not observed in the case of the platinum(II) complex [Pt(trpy)C ≡ CPh](OTf) (PtH), wherein the emission intensity based on metal-to-ligand charge transfer/ligand-to-ligand charge transfer was increased.
