摘要

The nonlinear optical property of new polyester has been studied via second harmonic generation (SHG). The values of electro-optic coefficients, d33 and d31, of the poled polymer film were 3.15× 10~(-7) and 1.5×10~(-7) esu, respectively. Thermal behavior of this polyester was studied through thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). 4-di-(2'-hydroxyethoxy)-4-diphenyl-hydrazonomethyl was synthesized from the reaction of 3,4-dihydroxy-4-diphenyl-hydrazonomethyl with 2-chloro-1-ethanol in a 1:2 mole ratio and subsequently reacted with terephthaloyl chloride (TPC) in the presence of pyridine, as catalyst, to produce the new nonlinear polyester. The chemical structures of the resulting monomers and polymer were characterized by CHN analysis, ~1H-NMR, FT-IR, and UV-Vis spectroscopy.
