Determination of the First Hyperpolarizabilities of Octupolar Molecular Ions Made from Symmetric Cyanine Dyes

Symmetric cyanine dyes of the kind Me2N+CH(CHCH) n NMe2 normally exhibit no first hyperpolarizabilities β but have relatively long absorption wavelengths. Therefore they are not suitable NLO chromophores for second-order applications. However, if these chromophores are converted into octupolar m...
