Nlo Properties

 The present work aims to study the second-order NLO properties of m-AD and p-AD regioisomers. The βtot value of p-AD is larger than that of m-AD. Significantly, the external electric field effectively regulates the βtot values (0–3.70 × 104 a.u.) of p-AD.

The Cross

The time-evolution of many-electron systems induced by an electric field in the instantaneous limit is an effective tool for investigating computationally nonlinear optical properties. It works well also for those cases in which the convergence of the perturbative expansions of the cross sections is challenging.

Phthalocyanine Ring

Electric Field Induced Second-Harmonic (EFISH) Generation and Hyper Raleigh Scattering (HRS) measurements were performed on a representative series of axially substituted titanium(IV) and gallium(III) tetra-tert-butylphthalocyanines. The comparison of γEFISH and βHRS values within the series and in particular in the case of the dimeric species shows the influence of both the reduction of symmetry of the phthalocyanine ring and the intramolecular stacking on the second order nonlinear optical properties.
