Behavior of Supramolecular Polymerization of Alkynylplatinum(II) Complex in Different Compositions of DMSO and Water.

ABSTRACT: We report the self-assembling behavior of a terpyridine-based alkyne platinum(II) complex (R-L-Pt-BP) under varying composition ratios of DMSO and H₂O. The resulting self-assemblies exhibited distinct photoluminescence and circular dichroism (CD) properties depending on the solvent conditions. Notably, strong positive CD signals were observed for the self-assembled R-L-Pt-BP in DMSO and H₂O (2:8 v/v), accompanied by a red-shift in emission wavelength. In contrast, a negative CD signal was observed for the self-assembled R-L-Pt-BP in DMSO and H₂O (5:5 v/v), along with a blue shift in photoluminescence (PL). The self-assembly formed in DMSO and H₂O (2:8 v/v) followed a cooperative model characterized by a nucleation-elongation mechanism, whereas th
