Enhanced NLO properties of molybdenum push–pull coordination compounds with tridentate ONO organic ligands

Superalkali nature of the Si9M5 (M = Li, Na, and K) Zintl clusters: a theoretical study on electronic structure and dynamic nonlinear optical properties

“…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.…”
