Abstract
Theoretical second hyperpolarizabilities for a series of iso-electronic conjugated inorganic systems, including polyphosphazenes, have been evaluated using electronic structure methods. The nonlinear optical properties of these molecules are controlled by the electronegativity difference along the backbone, which may be modulated by the electron donating/accepting properties of the ligands.
