Two state “ON–OFF” NLO switch based on coordination complexes of iron and cobalt containing isomeric ligand: a DFT study

Abstract

Coordination complexes are interesting materials for nonlinear optical (NLO) applications due to their large hyperpolarizability values.

Substituent and redox effects on the second-order NLO response of Ru(ii) complexes with polypyridine ligands: a theoretical study

“…[27][28][29][30][31][32] Their NLO responses are also easily modulated by modifying the ancillary ligands, redox and other parameters. [33][34][35][36][37][38] In 2003, Powell et al employed the hyper-Rayleigh scattering (HRS) procedure to measure the molecular quadratic optical nonlinearities of complexes M(4-CRCC 6 H 4 -NO 2 )(PH 3 ) 2 (Z-C 5 H 5 ) (M = Fe, Ru, Os). The obtained b HRS values were affected by the electron-withdrawing/donating characteristic of ligands.…”
