ABSTRACT:
Unconventional twisted π-electron system electro-optic (EO) chromophores/compounds, compositions and related device structures. Crystallographic analysis of several non-limiting chromophores reveals, for instance, large ring-ring dihedral twist angles and a highly charge-separated zwitterionic structure in the ground state, in both solution phase and solid-state.
