Abstract:

Two novel of nonlinear optical(NLO) organic material, chalcone derivatives(1-(furan-2-yl)-3-(4-methoxyphenyl) acrylketone(1) and 1-(thiophen-2-yl)-3-(4-methoxyphenyl) acrylketone(2)), were synthesized and characterized by NMR, IR and HR-MS. The third-order nonlinear optical properties were measured by the 4f phase-coherent imaging system and the resulting relevant parameters were given as following with 4 nm pulse width and 440 nm laser wavelength:for compound 1:nonlinear absorption coefficient β=5.5×10-10 m/W, nonlinear refractive coefficient n2=-2.1×10-17 m2/W, third-order nonlinear polarization χ(3)=1.58×10-11 esu; for compound 2:β=-2.4×10-10 m/W, n2=0.3×10-17 m2/W, χ(3)=0.50×10-11 esu. The corresponding UV absorption and DSC curves were also investigated. Moreover, their orbital energy and polarization calculated by density functional theory demonstrate that electron transfer can be easily conducted intramolecularly caused by the easy polarizability of the targeted products. These materials show good potential application as the NLO materials.
