Structural modulation of the dipolar-octupolar contributions to the NLO response in subthalocyanines

Article Abstract:

The second order nonlinear optical properties of a series of trinitrosubphthalocyanine (SubPc) isomers were studied by electric field induced second harmonic (EFISH) generation and hyper Rayleigh scattering (HRS). The results indicate that the dipolar contributions to the beta tensor are dependent on the substitution pattern at the periphery of the subthalocyanine macrocycle, whereas the octupolar contributions remain almost unchanged.
