An octupolar molecule with triazine as core, styryl conjugate and nitrogen-carbon double bond as bridge and hydroxy ethoxy as the donor group was designed and synthesized. The structures and properties of the organic molecules were characterized by IR, elemental analysis, 1H MNR, UV-Vis and DSC-TG. The second order nonlinear optical properties was determined by Kurtz-Perry powder method. The results show that the compound second-harmonic generation (SHG) equals to 1.7 times of potassium dihydrogen orthophosphate (KDP). The maximum absorption wavelength of the compound was 411.5 nm. The compound was thermally stable with the decomposition temperature of 397 . Consequently it could be ℃ considered to be a better choice for the preparation of nonlinear optical (NLO) materials.

Key words: second-order nonlinear, octupolar molecules, trimethyl-s-triazine
