Metallo-supramolecular complexes from mPEG/PDPA diblock copolymers and their self-assembled strip nanosheets.

ABSTRACT: Herein we designed and synthesized mPEG/PDPA copolymers containing two 4-([2,2':6',2''-terpyridin]-4'-yl) phenyl (Tpyp) groups at the junction point of the two blocks (mPEG(-b-Tpyp)₂-b-PDPA _x , x = 23, 33, and 44). Interestingly, after a hierarchical pattern from the coordination of mPEG(-b-Tpyp)₂-b-PDPA _x with Ru(ii) ions followed by the self-assembly in water, 2D strip nanosheets with a monomolecular layer were obtained. In contrast, mPEG(-b-Tpyp)₂-b-PDPA _x without coordination self-assembled into spherical micelles in the similar condition. The formation of the rigid and charged ⋯Tpyp-Ru(ii)⋯ chain, the brush-shaped polymer architecture and the presence
