Abstract :
Density functional theory was employed to investigate a series of phthalocyanine derivatives, discovering the limitation when the expansion of the conjugated system was employed to improve the hyper-Rayleigh scattering response coefficient. Furthermore, an unusually C ∞v -type octupolar population was found by electrostatic potential analysis. In addition, the dynamic and static hyper-Rayleigh scattering responses ( βHRS ) were simulated using the coupled perturbed density functional theory, showing an increasing dynamic βHRS value along with an increase in incident light energy.
