“…Theoretical investigation on charge transfer and NLO response of Lindqvist type POMs (hexamolybdate/molybdate anions) functionalized with side chains organic ligands showed that the charge transfer from molybdate central core to the ligands has a central role in the enhancement of the SHG and significant values of second-order polarizability can be obtained in such configuration. [316,317] In the same way, metal polycarboxylates [312,[318][319][320][321] based crystals have shown promising potentialities in terms of second harmonic generation. E. Cariati and co-workers reported several complexes using trans-4-(4-dimethylaminostyryl) - [320] In this case, the very large SHG is mostly explained by the important quadratic polarizability of the ligands DAMS + (much more important than the SHG from the metal-to-ligand charge transfers contribution) combined with their self-organization in a layered structure with an optimized J-type aggregate configuration (Figure 28).…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

“…An NLO response exhibit by organic compounds is often superior to those of pure inorganic materials [15,16]. Therefore, in this field organometallic compounds possessing NLO properties have opened new doors of achievement whereas search of new materials with greater NLO response are still in progress.…”

In this study, the energy gaps, second-order nonlinear optical (NLO) properties and dipole polarizabilities of triphenylamine based α-cyanocinnamic acid acetylene derivatives have been investigated via using time-dependent density functional response theory. These compounds were designed theoretically by fluorine (F) atom substitution at different positions of phenyl ring end of the α-cyanocinnamic acid segment. The results have indicated that the systems substituted by fluorine show remarkable NLO second-order response, especially D4 system with computed static second-order polarizability (βtot) of 70537.95 (a.u). Hence, these materials have the likelihood to be an excellent second-order nonlinear optical (NLO) materials. The βtot value suggests that along the x-axis the charge transfer (CT) from triphenylamine to α-cyanocinnamic acid (D-A) plays a key role in NLO response; whereas α-cyanocinnamic acid acts as an acceptor (A) and triphenylamine acts as a donor (D) in all the studied systems. Incorporation of an electron acceptor (F) at the phenyl ring end of the α-cyanocinnamic acid segment increases the computed βtot values. The present investigation therefore provides an important insight into the remarkably greater NLO properties of α-cyanocinnamic acid and triphenylamine attached via acetylene.
