“…5 Literature reveals that not only the hyperpolarizability but also third-rank NLO responses are equally contributing to achieving modern-day optical technologies such as optical data storage, optical communication, biological imaging, and signal processing. [6][7][8] For obtaining exceptional NLO features in molecule systems, numerous techniques have been proposed in the literature, such as utilizing the push-pull mechanism, 9 creating the metal-organic framework, 10 introducing diradical character in the conjugated system, 11 designing multidecker sandwich complexes, 12 and induction of excess electrons in molecules. 13 Since Dye et al carried out an innovative study of excess electron compounds based on cryptand and crown ether, 14 the signicant impact of excess electrons on the hyperpolarizability of molecules and clusters gives rise to new prospects for designing and exploring high-performance NLO materials.…”

Six new cis‐dioxidomolybdenum(VI) complexes featured with a tridentate ONO donor Schiff base derived from salicylidene‐2‐aminophenolato backbone have been synthesised and characterised by elemental analysis, spectroscopic techniques (like IR, UV‐vis and 1H‐NMR) and cyclic voltammetry. Suitable single crystals of the parent complex [MoO2L(MeOH)]2·H2O (1) was obtained by the slow evaporation of the mother liquor, whereas the crystals of the complexes 2‐6 were grown in coordinating solvents like ethanol, DMF, DMSO etc. and were characterised by single crystal X‐ray diffraction as monomers stabilised by the solvent molecules used for the recrystallization purpose. The structures of the complexes were further quantified using Hirshfeld surface analysis. The Schiff base acts as a colorimetric chemosensor for CN‐ ions in DMSO solution. The receptor‐CN‐ ion interaction and the sensing mechanism of the chemosensor were verified by colorimetric, UV‐vis, 1H‐NMR and FT‐IR spectroscopic studies. Hydroxyl moiety present in the receptor function as the binding site for cyanide ion thereby leading to its optical discrimination in presence of other anions by producing a visible colour change from colourless to yellow. Therefore the Schiff base sensor portrays estimable selectivity and sensitivity towards CN‐ ion. Additionally the Schiff base as well as the molybdenum complexes exhibit good third order non‐linear optical properties and optical power limiting when analysed by the Z‐scan technique.

Unsymmetric Schiff‐base metalloligand precursor 2 is synthesized by condensation of phenol‐functionalized ferrocenylenaminone 1 with 2‐hydroxy‐5‐nitrobenzaldehyde. Heterobimetallic complexes 3 and 4 result from the N2O2‐tetradentate coordination of NiII and PdII metal ions with the doubly deprotonated form of 2, respectively. Linking 3 and 4 to polyacrylic acid through an esterification reaction leads to the formation of the corresponding side‐chain metallopolymers 5 and 6. The new compounds were fully characterized (IR, UV/Vis, NMR, MS, CV, SEC) and structures of 2–4 unequivocally determined by single‐crystal X‐ray diffraction techniques. Decomposition temperatures higher than 250 °C were found by DSC and TGA techniques for 3–6. Harmonic light scattering measurements showed that compounds 2–5 exhibit rather high second‐order nonlinear responses, between 200 × 10–30 and 970 × 10–30 esu, with the hyperpolarizability β1.91 value increasing significantly on passing from NiII complex 3 to its respective metallopolymer 5. The structural and electronic properties of 2–4 are analyzed by DFT and TD‐DFT calculations.
