Synthesis of organic salts with large second-order optical nonlinearitiesThe variation of the anion counterion in the presently formulated organic salts, whose cation possesses large molecular hyperpolarizability, will in many cases yield materials with large powder second-harmonic generation efficiencies. The highest such efficiency is three orders of magnitude greater than that of the urea used as a reference compound. It is demonstrated that such nonconventional donors as Br(-) and the pyrenyl moiety can be incorporated into molecules which, in the requisite crystallographic environment, will exhibit substantial bulk susceptibilities.
