“…In addition to the significance of closed-shell luminescent materials of coordination compounds in the aforementioned fundamental research areas, they have been receiving a great deal of attention in applied research in several different areas. These include photonics (e.g., molecular LEDs and laser materials), nonlinear optics, optical sensing of environmental pollutants, solar energy conversion, photocatalysis, luminescent probes for biological systems, optical telecommunication, photoinduced magnetic switching, optical writing, and various inorganic conducting and semiconducting materials …”

Spectroscopic and bonding properties of Hg(n) oligomers and *Hg(n) exciplexes are determined by rigorous theoretical treatments. Reliable values that agree well with experimental data have been computed for the luminescence energies and other molecular spectroscopic parameters by making a careful selection of theoretical methods and basis sets. The calculations clarified the assignments for several phosphorescence bands in the mercury vapor based on calculated energies and other parameters that quantify the large excited-state distortion in the emitting states. Both the weak ground-state mercurophilic bonding and the stronger covalent bonding in the triplet and quintet excited states studied are found to be cooperative, which is important for fundamental and applied research for luminescent and magnetic materials that have spectral behavior similar to that of Hg(n) systems.

“…Schiff base compounds characterized by the imine linkage appear to be a good source for a series of compounds that may show good second harmonic generation. These compounds may be either in the solid crystalline form or in the form ofliquid crystals, or may be incorporated into polymers or can be used in organometallic compounds to show second -order and third order nonlinearity (5). They possess a non-centrosymmetric configuration, either in the molecular or crystalline unit cell.…”

Synthesis, characterization, and bulk crystal growth of nonlinear 3-substituted salicylidene aniline derivatives

et al. 2003

Salicylidene-aniline (SA) derivatives have been synthesized and characterized for optical and nonlinear optical properties. The substituents used are methyl (-CH3), chloro (-Cl), and the nitro (-NO2) groups. These substituent groups show a variation in their electro-negativity characteristics and hence have the capacity to perturb the electrons system in the parent ring structure of the salicylidene-aniline compound. Material characterization has been done using various analytical tools namely: DSC, FTIR, UV-VIS and GC/MS. The nonlinear optical characterization has been done using the Kurtz powder efficiency method. The nonlinear refractive index and the third order susceptibility have been determined using the Z-Scan method in solution using ethanol as the solvent. The Kurtz powder efficiency measurements using urea as standard gives the values as 0.7 for 3-Cl SA, 0.8 3-NO2 SA and 1 .0 for the 3-CH3 SA derivative. The results of single bulk crystals grown using the Bridgman -Stockbarger method are reported.
