A novel supramolecular ternary polymer mediated by macrocyclic molecules cucurbit[8]uril (CB[8]) and cyclodextrin was successfully constructed, based on the CB[8]-stabilized charge-transfer (CT) interaction cyclodextrin–adamantane host–guest interaction. Herein, we synthesized a naphthol-modified β-cyclodextrin (Np-β-CD) an adamantane–viologen ditopic guest to obtain complex with preorientational donor–acceptor pair. Furthermore, after addition of CB[8] complex, pair naphthol–viologen encapsulated into cavity leading linear which well characterized various methods, including DOSY, DLS, SEM, TEM AFM. This work enriches field polymers provides method fabricate architectures multiple host molecules.
