- Abstract
- Resorcin[4]arene-based cavitand bearing four benzimidazolamido moieties on the upper rim has vase conformation by the clip-type hydrogen bonds of a methanol with C=O as well as -NH of a benzimidazolamido unit. These methanol-mediated rigidifications of four benzimidazolamido moieties result in a narrow and deep cavity, and the aromatic protons in the -NH side of benzimidazolyl unit direct to adjacent benzimidazolyl unit. This methanol-mediated cavitand forms weak complexes of n-alkanes by CH/pi interaction with the aromatic it surfaces of the walls at low temperature. (C) 2013 Elsevier Ltd. All rights reserved.
