Abstract :
Three compounds with three p-substituted styryls attaching to the central s-triazine have been synthesized and two crystals determined to be in non-centrosymmetric Cmc21 and Pmn21 space groups, respectively. All of them in solid state are second harmonic generation (SHG) active and two of them show powder SHG intensities one order of magnitude that of urea.
