Molecular capsules of tetrakis(N-hydantoinylimino)cavitand: Selective encapsulation of 1,4-diiodobenzene

초록

Resorcin[4]arene-based iminocavitand 2 with four hydantoinyl moieties was designed and synthesized. This cavitand 2 self-assembled into thermally stable molecular capsules G@2(2) in the presence of suitable guests through 8 intermolecular hydrogen bonds of imide N-H center dot center dot center dot O=C, two for each four paired hydantoinyl units. Molecular capsule 2(2) showed selective complexation for p-disubstituted benzenes, especially for 1,4-diiodobenzene. (C) 2017 Elsevier Ltd. All rights reserved.
