Large two-photon absorption cross sections in two-dimensional, charge-transfer, cumulene-containing aromatic molecules
Ab initio simulations of two-photon absorption in donor-acceptor substituted cumulene-containing aromatic molecules have been carried out. The results reveal that these two-dimensional, charge-transfer species possess particularly large two-photon absorption in the visible region with possible applications for optical limiting.
