제목 Supramolecular Capsules with Gated Lateral Pores from Amphiphilic Rod Assembly
초록 Self–organization of lipids into membrane structures has inspired synthetic self-assembly system in constructing membranous capsules with encapsulation and release capabilities, by gated openings. However, self–assembly of synthetic molecules has only yielded closed capsules, and pores in few examples of porous capsules reported do not have gating function. Therefore, self–assembled synthetic capsule structures with the gated openings remain to be explored. Here we show the formation of a capsule structure with gated lateral nanopores, which is based on the 2D self–assembly of dumbbell–shaped rod amphiphiles. The porous capsules undergo thermoresponsive reversible transitions from the open state, through which cargo molecules can flow, to the closed state upon heating, capable of entrapping the cargos. We anticipate that our findings will provide a new strategy for designing a variety of stimuli-responsive synthetic systems with biomimetic functions.
