Abstract
Nonlinear optical (NLO) compositions are disclosed which contain polar disulfone-functionalized molecules (PDFMs) incorporated in a polymeric material. When aligned noncentrosymmetrically in the polymeric material, the PDFMs generate a second-order NLO response. There is also disclosed: a method of preparing a NLO composition; novel PDFMs and novel polymers; and a new process for preparing PDFMs.
