Three novel malononitrile derivatives have been synthesized by the solid state reaction at room temperature. The reactions are carried out for 0.5 h with yields all beyond 93%. The compounds have been characterized by IR、 UV 、 1H NMR and elemental analysis. The structure of the compound 3 is determined by X-ray diffraction analysis. The single- and double-photon fluorescence spectra of the compounds 2 and 3 are discussed. The results show that single-photon and double-photon fluorescences have similar solvent effect.
