摘要：
We report on the supramolecular polymerization of Pt(II) complex with terpyridine-based ligand (1) possessing alanine moiety in nonpolar solvents, such as methylcyclohexane, n-hexane, chloroform, and dichloromethane. The supramolecular polymer 1-Pt exhibited a strong orange emission as low as micromole concentration, which originated from the MLCT of 1-Pt in J-aggregation. The lifetime of supramolecular polymer 1-Pt was 0.5-2.1 mu s in nonpolar solvents. The supramolecular polymer 1-Pt showed a typical fiber structure using scanning electron microscopy (SEM) observation. Besides, the supramolecular polymer 1-Pt was generated by a cooperative pathway involving a nucleation-elongation mechanism.
