含氟芳香查尔酮衍生物的合成与三阶非线性光学性质
Synthesis and Third-Order Nonlinear Optical Properties of Fluorinated Aromatic Chalcone Derivatives
摘要
Abstract
Four novel chalcone derivatives were synthesized:1-(2,3-difluorophenyl)-3-(3-chloro thiophene-2-yl)-2-propene-1-ketone(0208#),1-(2,4-difluorophenyl)-3-(5-phenylthiophene-2-yl)-2-propene-1-ketone(0809#),1-(2,3-difluorophenyl)-3-(5-phenylthiophene-2-yl)-2-propene-1-ketone(0808#),1-(2,6-difluorophenyl)-3-(5-phenylthiophene-2-yl)-2-propene-1-ketone(0812#).The structures and properties of the compounds were characterized by 1 H NMR,13 C NMR,liquid chromatography-mass spectrometry,ultraviolet-visible spectrum(UV-Vis)absorption spectrum,fluorescence emission(EM)spectrum and Z-scanning technique.The energy and polarizability of the highest occupied molecular orbitals(HOMO)and the lowest unoccupied molecular orbital(LUMO)of the four compounds were obtained by density functional theory,and significant intramolecular charge transfer was found from orbital electron cloud images.The combination of large π-conjugation and charge transfer makes the four aryl chalcone derivatives exhibit good nonlinear optical properties.They can be used as useful candidates for nonlinear absorption(NLA)and have potential applications.关键词
