Abstract:

A novel dichalcone derivative, 1, 4-bis [3- (3, 4, 5-trimethoxyphenyl) -2-acryloyl] benzene (BTAB), was synthesized and characterized by nuclear magnetic resonance (NMR) spectroscopy and liquid chromatography-mass spectrometer (LC-MS). The thermogravimetry (TG) /differential scanning thermogravimetry (DSC) analysis shows that the melting point of the compound is 230.6℃ and the thermal stability is good. The maximal wavelengths of ultravioletabsorption and fluorescence emissions are determined as λmax/UV=357.5 nm, λmax/EM=541 nm, respectively. The energies of the highest occupied and lowest orbital of molecules and polarizability of BTAB were obtained using the density functional theory method. The phenomenon of intramolecular charge transfer was also found from the molecular orbitals. The optical nonlinearities of the BTAB was confirmed by the single beam Z-scan technique. The third-order nonlinear absorption coefficient β and the fifth order nonlinear absorption coefficient γ are 3.15×10-14m/W and 2.7×10-28m3/W2, respectively, which belongs to double photon absorption. All these results demonstrate that the chalcone ketones BTAB is promising for non-linear optical applications.
