چکیده انگلیسی
A novel supramolecular polymer based on cucurbit [8] uril host-stabilized charge-transfer (CT) interactions between a viologen dication (MV2+) connector and a cyano-stilbene fluorophore decorated with dimethylamino portion has been constructed. Its reversible association and dissociation can be well controlled by electrochemical and pH stimuli, with two pseudorotaxanes worked as monomers induced by respective excitation. 1H NMR experiment, 2D NOESY NMR, DLS and AFM measurements were employed to demonstrate the formation of linear supramolecular polymer. Fluorescent and cyclic voltammetric experiments were carried out to illustrate its reversible assemble/disassemble process vividly.
