Structure-Property Relationship of Three 2-Chloro-4-fluoro Chalcone Derivatives: A Comprehensive Study on Linear and Non-linear Optical Properties, Structural Characterizations and Density Functional Theory
2022, Journal of Molecular StructureCitation Excerpt :The structure of chalcone derivatives can be tailored to investigate their structure-property relationship. Recent literature highlights a high optical nonlinearity for chalcones are attributed to the π-electron conjugated system, which affords intramolecular charge transfer (ICT) within the molecule and decreases the energy gap [29–31]. It has also been shown that the 3rd order optical non-linearities grow with push-pull effect from donor/acceptor (D/A) substituents [32,33], substituted donor/acceptor strength [34,35] and relative position [36], conjugation length [37], intermolecular interactions [38–40], molecular planarity [41–43] and conformation [44], etc.

2020, Advances in Imaging and Electron PhysicsAn investigation on photophysical and third–order nonlinear optical properties of novel thermally–stable thiophene–imidazo [2,1-b][1,3,4] thiadiazole based azomethines
2019, Dyes and PigmentsCitation Excerpt :The superposition of pz atomic orbitals of carbon in conjuagated system facilitate the movement of π–electrons in large molecular orbitals. The planarity and rigidity of conjugated backbone optimizes the overlapping of π–orbitals which results in enhanced electron delocalization, leading to the enhancement in optical nonlinearity which increases with the extension of conjugation [50–52]. In the present work, both the molecules TI1 and TI2 possess thiophene as strong electron donor and ITD as an electron acceptor moiety, which provide a D–A type arrangement.
