Encapsulation of charge-diffuse peralkylated onium cations in the cavity of cucurbit[7]uril

Encapsulation of charge-diffuse peralkylated onium cations in the cavity of cucurbit[7]uril

Cucurbit[7]uril binds, with considerable size selectivity, NR(4)(+), PR(4)(+), and SR(3)(+) cations (R=Me, Et, (n)Pr, (n)Bu), with the smaller guests inside its cavity, rather than at the carbonyl-lined portals.
