Abstract

A variety of disubstituted diphenylacetylenes and related compounds have been synthesized by a modified Horner–Emmons reaction, and their second harmonic generation (SHG) has been evaluated by the Kurtz powder method. The diphenylacetylenes with weak electron-donating and-withdrawing groups are found to be efficient for SHG, as well as having the lowest cut-off wavelength.
