Abstract: The present invention is directed, in general, to nonlinear optical chromophores having an indolizine donor group. Various embodiments of the present invention include nonlinear optical chromophores with indolizine donor group having an indolizine donor connected to a II-bridge group. In various preferred embodiments of the present invention, the indolizine donor groups may be substituted or unsubstituted, including hydro and alkyl substituents, aryl substituents and combination thereof.
