Tunability of guest release properties and crystal structures in a supramolecular benzothiophene heterocyclic host complex?
CrystEngComm Pub Date: 2015-01-20 DOI: 10.1039/C4CE02496F
Abstract
A supramolecular benzothiophene heterocyclic host complex was successfully prepared by combining benzo[b]thiophene-3-acetic acid and chiral (1R,2S)-2-amino-1,2-diphenylethanol. Four types of n-alkyl alcohols could be stored as guests in one-dimensional channel-like cavities composed of 21-helical columnar network structures. The release temperatures of the stored guest alcohols could be multiply tuned according to the type of the benzothiophene unit in the complex.
