Abstract:A novel substituent styryl pyridinium tetraphenylborate, 4-N,N- dimethylamino -4’-N’- 9-methanoanthracene-stilbazolium tetraphenylborate, has been synthesized and characterized by IR spectrum and X-ray single-crystal diffraction. The complex crystallizes in monoclinic space group P21/c with a = 1.2557 (1) nm, b = 1.539(1) nm, c = 2.2202 (8) nm, β =101.099(1) °, and V = 4.2105(4) nm3, Z = 4, Dc = 1.159 g•cm-3. In the title molecule, the pyridyl ring of the cation makes dihedral angle of 2.8° with the phenyl ring. The nonlinear optical properties of the compound were investigated by virtue of 1064 nm nanosecond laser beam, and the results show that the novel pyridinium salt has a TPA coefficient of β= 0.028 cm/GW, a TPA cross-section of σ= 8.68×10-48 cm4•s•photon-1. | |||
