(Chemical Equation Presented) Nonlinear optics: Twisted π-electron system electrooptic (EO) chromophores with exceptional molecular hyperpolarizabilities (-488 000×10-48 esu at 1907 nm) were designed and synthesized. Crystallographic analysis reveals large twist angles and a highly charge-separated zwitterionic ground state. Experiments on poled host-guest polymers containing these chromophores show them to be promising candidates for EO applications.
