Reversible encapsulation allows the temporary isolation of molecules in very small spaces. There, molecular behavior is quite different than that in bulk solvent; in capsules recognition can be amplified, reactive intermediates can be stabilized, reactions can be accelerated or even catalyzed and new reaction pathways can appear. Accordingly, a multitude of capsules have been devised over the l...

Abstract Enhancing the proton conductivity of exchange membranes (PEMs) is essential to expand applications membrane fuel cells (PEMFCs). Inspired by conduction mechanism bacteriorhodopsin, cucurbit[ n ]urils (CB[ ], where number glycoluril units, = 6, 7, or 8) are introduced into sulfonated poly(ether ether ketone) (SPEEK) matrix fabricate hybrid PEMs, employing a nature-inspired chemical engi...
