On the basis of ZINDO methods, according to the sum-overstates (SOS) expression, the program for the calculation of the second-order nonlinear optical susceptibilities βijk and βμ of molecules was devised, and the structures and nonlinear optical properties of unsymmetric bis(phenylethynyl) benzene series derivatives were studied. The influence of the molecular conjugated chain lengths, the donor and the acceptor on βμ was examined.
Nanostructured materials have drawn considerable attention because they are promising candidates for nextgeneration electronic and photonic devices with low power consumption[1-5]. A number of methods, such as laser ablation[6], template-induced growth[7], arc discharge [8], vapor transport [9], and molecular-beam epitaxy[10] have been developed to synthesize Si, Ge, MgO,SnO2, GaN, and Ga2O3 nanowires or nanorods[11-15].……
