Abstract
Inclusion complexes, comprising a host and a guest, that exhibit greater second harmonic generation efficiency than either the host or the guest exhibits by itself. Preferred hosts can be selected from cyclodextrins, cyclodextrin derivatives, and cyclodextrin polymers. Preferred guests can be selected from aromatic compounds in which the molecule contains both an electron-donating functional group and an electron-withdrawing functional group.
