The results of three independently strategies for the optimizations of electro-optic organic chromophores is presented. The first strategy to enhance the nonlinear optical response, applied at the molecular level, is the extension of the conjugation path in a ionic chromophore. The second strategy, applied at the supramolecular level, is the bottom-up nano-engineering of an inclusion complex of the ionic chromophore in an amylose helix. The third strategy, also applied a the molecular level, is to use a modulated conjugation path between donor and acceptor in order to localize eigenfunctions on different parts of the molecule. The first hyperpolarizability of the different series of compounds has been experimentally determined by frequency-resolved femtosecond hyper-Rayleigh scattering. The effects of the three different enhancement strategies are analyzed and interepreted in terms of the quantum limits.
