The structures and properties of [n]sila-acenes (n=2-4) were investigated by density functional theory method. The results of calculations were obtained at B3LYP/6-311G (d,p) level on model species. Energetic criteria suggest that 2-1b (n=2), 3-1b (n=3), and 4-1b (n=4) isomers enjoy stabilization. By frontier orbital analysis, these systems are among the most stable of the family. Also, calcula...

Nonlinear optical (NLO) materials have highly interesting photo-physical behaviors, which a wide variety of applications, from optoelectronics to medicine. NLO properties together with infrared (IR) and nuclear magnetic resonance (NMR) analyses on the interaction between hydroquinone (HQ) pristine boron or silicon doped C60 fullerene systems been investigated by density functional theory (DFT)....
