Toward the design of inorganic–organic hybrid Ir(III) complexes containing borazine and benzene ligands with excellent second-order NLO responses: An appropriate substitution and π-conjugated extension

A theoretical study on the second-order nonlinear optical properties of Pt(ii) bis-acetylide complexes: substituent and redox effects

“…The NLO properties of complexes constituted by a variety of transition metals, such as Ir( iii ), Ru( ii ), and Pt( ii ), have been investigated due to their good thermal and photochemical stability. 22–29 In 2010, Valore et al reported that cyclometallated Ir( iii ) complexes with a β-diketonate ligand were characterized by an unexpected large second-order NLO response and their NLO response could be modulated by modifying ligands and redox, etc. 30 In 2014, Dragonetti et al reported a series of [Ir(ppy-4-CHCHPhR) 2 (MeCOCHCOMe)] (R = NEt 2 , OMe, H, NO 2 ) complexes and they observed that the presence of a strong electron-donating (–NMe 2 ) or electron-withdrawing (–NO 2 ) group could significantly improve the NLO response of the complex.…”

Investigation Nonlinear Properties (First and Second Hyperpolarizabilities) of The Nitro-thieno [3,2-b] thiophene -fullerene (C20) Molecule

“…Almost all NLO materials in the last 30 years were made of inorganic crystals 4 . Because organic materials have greater NLO responses than inorganic counterparts, there has recently been a paradigm shift toward them [5][6][7] . Moreover, they may be made cheaply, and they form high-quality crystals quickly.…”

Theoretical Perspective on Two-State “ON–OFF” NLO Switch of Rh(III)-Azobenzene Complex with Considerable First Hyperpolarizability

“…Since then, the search for functional materials with nonlinear optical (NLO) property has never been stopped . In the past few years, intensive endeavors have been focused on the design and synthesis of novel materials with excellent NLO responses owing to their extensive use in optical limiting, data storage, frequency conversion, and other fields. − There are tremendous efforts to develop various classes of NLO materials. In general, the NLO properties of organic materials have the advantages of large NLO responses, more flexible molecular design, fast optical response, and low cost. − Hence, organic NLO materials have been a widely explored theme to the area of NLO since its inception.…”
