In this poster, a new method of supramolecular polymerization promoted and controlled through self-sorting is reported. The bifunctional monomer containing p-phenylene and naphthalene moieties is prepared. Supramolecular polymerization is promoted by selective recognition between the p-phenylene group with cucurbit[7]uril (CB[7]) and 2:1 complexation of the naphthalene groups with cucurbit[8]uril (CB[8]), and can be controlled by tuning the content of CB[7]. Additionally, Asymmetric Flow Field Flow Fractionation is firstly introduced to characterize the supramolecular polymers to obtain specific information about molecular weight and polydispersity. This research will enrich the field of supramolecular polymers with important advances towards the realization of molecular weight and structural control.
