Origin of the second harmonic generation in a supramolecular inclusion complex between p-nitroaniline and beta-cyclodextrin

摘要

We report a combined NMR and crystallographic study of a supramolecular complex of beta-cyclodextrin with p-nitroanaline. We show how the guest induces the formation a channel structure in the host cyclodextrin and discuss the guest molecule orientation and disorder in terms of the potential non-linear optical activity of the non-centrosymmetric crystals.
