Abstract
|
Supramolecular gels made from 2D building blocks are emerging as one of the novel multifunctional soft materials for various applications. This study reports on a class of supramolecular nanosheet gels formed through a reversible self–assembly process involving both intramolecular folding and intermolecular self–assembly of poly[oligo(ethylene glycol)–co–(phenyl–capped bithiophenes)]. Such hierarchical self–assembled structure allows the gels to switch between sol and gel states under either redox or thermostimulus. Moreover, the gels illustrate high Young´s moduli, compared to their controls that are made from the same oligo(ethylene glycol) and phenyl–capped bithiophenes blocks but have highly covalent–crosslinked structures. The example might open a window for emerging supramolecular 2D materials to develop mechanically robust and stimuli–responsive soft materials without compromising their intrinsic functions.
