A layer-by-layer assembled D/L-arginine-calix[4]arene-Si-surface for macroscopic enantio-selective discrimination of (R)/(S)-ibuprofen

Chem Commun (Camb). 2021 Jun 8;57(46):5706-5709. doi: 10.1039/d1cc01307f.

Abstract

Chiral arginine was introduced by layer-by-layer assembly onto a calix[4]arene-diacid modified silica surface to control the adsorption of different kinds of ibuprofen droplets. The droplet of (S)-ibuprofen slid off rapidly, whereas the droplet of (R)-ibuprofen absorbed on the modified surface.
