摘要:A novel third-order nonlinear optical (NLO) crystal based on the organic borate carboxylate ester, with formula [Na-4(H2O)(5)][B{O2CCH(O)Ph}(2)](4) (abbreviated as LMBNa), has been prepared in aqueous solution. Single-crystal X-ray diffraction analysis reveals that the boron atom is coordinated with two L-mandelic ligands by alkoxide and carboxylate groups, forming the [B{OOCCH(O)C6H5}](-) anion. The sodium cation supports its structural framework of borate anions in the formation of a cross-linked structure. Bulk single crystals of LMBNa were grown from acetonitrile/water by the temperature lowering method. Studies of its third-order NLO properties using a Z-scan technique demonstrate that the LMBNa crystal possesses a strong saturable absorption and the self-focusing effect. Its second molecular hyperpolarizability (gamma) at 532 nm is calculated to be (3.9 +/- 0.2) x 10(-31) esu. Furthermore, dielectric experiments reveal that LMBNa has a quite low-dielectric constant (similar to 3.43) and shows an anisotropy of frequency dependence along the different crystallographic directions. Such dielectric behaviors will favor the application of the LMBNa crystal under the electric field. All the results indicate that LMBNa might be a potential candidate material for the third-order NLO applications.
