An organic octupolar molecule with active hydroxyl groups was designed and synthesized. The structure and propertie of the organic molecule was characterized by IR,1H MNR, UV-vis and DSC-TG. The maximum absorption wavelength of the compound is 439 nm. The critical wavelength is below 710 nm. The compound is thermally stable with the decomposition temperature of 401°C, and consequently could be considered to be a better choice for the preparation of NLO material.
