New Organic and Organometallic Materials with Nonlinear Optical Properties for Optical Signal Processing.
Abstract
Of the molecules measured with EFISH there is a striking constancy of their microbeta products and even the more approximate beta's themselves. These molecules are all nitrobenzene derivatives and the observation could be made that the magnitude of beta is more or less tied to this conjugated portion of the molecules. Comparison of the power data with the molecular hyperpolarizabilities illustrates that a study of powder response tells essentially nothing whatever about molecular properties. Attention should be directed to crystal studies in the search for materials destined for application to the processing of weak optical signals. The dependence of molecular polarizability on concentration in some solvents for some solutes at very low concentrations has not been clearly seen before. These measurements were all made on solutions of less than 1 molecular percent and so solute-solute interaction almost certainly is absent.
