 Supramolecular polymers are of great interest because the nature of non-covalent
interactions holding them together imparts dynamic, reversible and degradable characteristics
to these materials. We have been developing new strategies to fabricate supramolecular
polymers, leading to advancement of controlled supramolecular polymerization. One is multi-
step self-assembly, which includes covalent preparation of ditopic monomers and
supramolecular polymerization of the ditopic monomers. In recent year, we have reported a
series of supramolecular polymers based on host (Cucurbit[8]uril) enhanced interactions, such
as host-enhanced charge transfer interactions and host-enhanced π-π interactions. Several
strategies are employed to promote the supramolecular polymerization, such as the select of
systems with high binding constants, the design of ABBA-type of monomers, the adoption of
into PSt-b-PAA micellar cores, and then employed the pyrene loaded block copolymer
bulky linkers. Based on these strategies, supramolecular polymers with high degree of
polymerization are achieved in dilute aqueous solution, while the dimerization and cyclization
are successfully prohibited. In addition, we have developed controlled supramolecular
polymerization by self-sorting recognition process . Another method involves so-called mixed
strategy, including non-covalent preparation of supramonomers and covalent polymerization
of the supramonomers. It is highly anticipated that these studies enrich the fabrication methods
of supramolecular polymers, but also facilitate the molecular weight and structure control of
supramolecular polymers.
