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.

具有高杨氏模量的氧化还原响应性和热响应性超分子纳米片凝胶
由2D构件制造的超分子凝胶正在成为用于各种应用的新型多功能软材料之一。这项研究报告了通过可逆的自组装过程形成的一类超分子纳米片凝胶,该过程涉及聚[低聚(乙二醇)-co-(苯基封端的联噻吩)]的分子内折叠和分子间自组装。这种分层的自组装结构允许凝胶在氧化还原或热刺激下在溶胶和凝胶状态之间切换。此外,与由相同的寡聚乙二醇和苯基封端的联噻吩嵌段制成但具有高度共价交联结构的对照相比,这些凝胶具有较高的杨氏模量。
