Abstract
Using the hyper-Rayleigh and the Z-scan techniques, we determined the first and the second hyperpolarizabilities of molecules containing mesoinic rings. We also present quantum chemical calculations for both hyperpolarizabilities that are in a good qualitative agreement with experimental results. Optical Kerr gate measurements indicate response times faster than 60 fs for these compounds which possess intrinsic push-pull characteristics and are promising substitutes for polyene bridges in photonic applications.
