Abstract:
A novel water-soluble supramolecular dendronized polymer (SDP) was prepared through cucurbit[8]uril (CB[8])-naphthalene host-guest interaction. The composition ratio between BDP and CB[8] of as-prepared luminescent supramolecular polymer was confirmed by 1H NMR technique and mass spectrometry. In addition, atomic force microscopy (AFM) images showing the polymer chain length up to 150 nm and height up to 1.75 nm unambiguously demonstrate the supramolecular polymer formation. This work might be useful for designing other main chain supramolecular dendronized polymers.

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
