First hyperpolarizability of organotin compounds with <i>T</i>_<i>d</i> symmetry

Abstract

A new class of nonlinear optical materials , tetrahedral tin complexes in which the metal ion can act as a polarizable group linked to donor dimethylamino moieties, is described. An example is shown in the Figure. The quadratic hyperpolarizability coefficients determined by hyper‐Raman scattering are reported and the important characteristics of the molecules discussed. magnified image
