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 = 23, 33, and 44). Interestingly, after a hierarchical pattern from the coordination of mPEG(-b-Tpyp)2-b-PDPA 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 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 of the hexafluorophosphate (PF6 -) counterions should be responsible for the unique self-assembly behavior of the metallo-supramolecular complexes. It is expected that the hierarchical self-assembly pattern can provide a new strategy for preparation of self-assemblies with different morphologies.
