Large two-photon absorption cross section : molecular tweezer as a new promising class of compounds for nonlinear optics

We report the highest two-photon absorption cross-section to date, obtained for a molecular tweezer complex. Our analysis suggests that long-range charge-transfer interaction in three dimensions is the main source of this very large two-photon absorption cross section.
