N,N-diphenyl-8-[2-(4-pyridinyl)ethenyl]-dibenzofuran-2-ylamine has been synthesized as a novel second-harmonic generation (SHG) material. From reflection measurement in powder form, the SHG of the titled compound is found to be nine times as intense as that of urea. An effective d coefficient by means of second-harmonic wave generated with the evanescent wave (SHEW) method is estimated to be 3 pm/V. The cutoff wavelength of the compound is 370 nm.
