Supramolecular Chemistry: Induced Circular Dichroism to Study Host-Guest Geometry
Mendicuti, Francisco; Gonzalez-Alvarez, Maria Jose
Journal of Chemical Education, v87 n9 p965-968 Sep 2010
In this laboratory experiment, students obtain information about the structure of a host-guest complex from the interpretation of circular dichroism measurements. The value and sign of the induced circular dichroism (ICD) on an achiral chromophore guest when it complexes with a cyclodextrin can be related to the guest penetration and its orientation relative to the cyclodextrin. This experiment examines the complexation of dimethyl 2,3-naphthalenedicarboxylate with 2-hydroxypropyl-alpha-, -beta-, and -gamma-cyclodextrins in aqueous medium. (Contains 2 tables and 5 figures.)
