Nonlinear optics (NLO) started to be explored by Franken et al., in 1961, with the discovery of second-harmonic generation (SHG) or frequency doubling. That happened right after the construction of the first laser by Maiman in 1960, of which the electric field intensity was sufficient to induce the nonlinear response of matter. Since then, NLO has started finding several applications with a growing impact on today’s daily life in different areas, such as lasers, interaction with materials and information technology. The interest in this field has led to the synthesis of several compounds over the years, both organic molecules and coordination complexes, in order to provide coherent light of different wavelengths, materials interaction through multi-photon absorption (photodynamic therapy in medicine, optical power limiting applications, etc.), advanced spectroscopy and materials analysis, possible applications to communications and sensors, and so on. This Special Issue aims to collect new advances in the synthesis, and experimental and theoretical characterization of new materials, ranging from purely organic derivatives to transition metal and lanthanide complexes, coordination polymers and hybrid systems, and description of their linear and nonlinear optical properties, such as SHG, multi-photon absorption, etc.Dr. Luca Rigamonti

Quinacridone-based nonlinear optical materials: From electronic, optical properties to two photon absorption
Abstract: Organic molecules with large second-order nonlinear optical (NLO) properties have been the focus of sizeable research efforts. Compared with conventional inorganic crystals, organic compounds have some merits: (a) optical damage threshold, and lower dielectric constant; (b) fast response time (10–14 s); (c) they are low-priced to produce; and (d) optical properties of compounds can be tunable by using chemical modification. Therefore, the compounds with D–A configuration are the archetypal molecules for quadratic hyperpolarizability, which were also found to exhibit two- or three-photon absorption cross-sections. Here, geometric structures, electronic, spectra and nonlinear optical properties (NLO) of Quinacridone-based NLO materials are investigated by means of quantum chemistry method and the response theory. The micro-mechanisms of first hyperpolarizability were explained on the basis of the two-level models, and charge difference density methods demonstrated mechanism of charge transfer under photo-excitation. Calculations of two-photon absorption (TPA) for Quinacridone-based molecules were performed to develop their potential application on TPA materials. Additionally, some molecules were designed by replacing electron donor moiety (such as triphenylamine, N,N-dimethylaniline, carbazole and azacrown ether and so on) to tune the NLO parameters in order to develop their utility in NLO materials.
