This study aims to prepare charge transfer complexes derived from organochalcogenide of arylamide derivatives with different quinones. A new charge-transfer complexes have been developed through a direct reaction between (PhNHCOCH2)2Se, (o-CH3PhNHCOCH2)2Se, and (PhCH2NHCOCH2)2E, where E = S, Se, and Te are electron donors and different quinones are electron acceptors. The quinones used in the reaction were 2,3-dichloro-5,6-dicyanobenzoquinones (DDQ), 7,7’,8,8’-tetracyanoquinodimethane, and tetracyanoethane. The electron donors and electron acceptor mol were 1:1, and the reaction was conducted in acetonitrile. Infrared, 1H and 13C-NMR spectroscopic data characterized all complexes. The complexes’ antioxidant activity was evaluated through α,α-diphenyl-β-picrylhydrazyl at 10–0.312 mg/mL. The results showed that all complexes exhibited promising antioxidant activities. Among them, (PhCH2NHCOCH2)2S·DDQ compound had the least IC50 value of 6.725 mg/mL, indicating a potent scavenging property compared to other compounds. The molecular structures of charge-transfer complexes were investigated using hybrid density functional theory (B3LYP) and basis set 3-21G. We obtained geometrical structures' highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) surfaces and energy gaps through geometric optimization. We also investigated the molecular shapes and contours of the prepared compounds through geometrical optimization and compared the HOMO energy of the CT compounds to investigate donor and acceptor properties.

“…Several fundamental investigations have been reported to prove these structure-property correlations. 58,59 The origin of such an enhanced nonlinear response in organic fluorophores could be attributed to the following key factors: (i) the presence of strong donor/acceptor units, (ii) conjugation length and (iii) photophysical properties like the intramolecular charge transfer (ICT) process. Two very crucial advantageous characteristics of the AA2 molecule is that it embraces a large p-conjugation system in the form of a thiophene p-bridge apart from possessing strong donor and acceptor units attached to it.…”

A set of four symmetric, butterfly‐shaped 4‐(4‐(decyloxy)phenyl)‐2,6‐di(thiophen‐2‐yl)pyridine (TPY) derivatives 2TPA‐TPY (TPY center and triphenylamine end groups), 2CBZ‐TPY (TPY center and N‐ethyl carbazole end groups), 2TPY‐TPA (triphenylamine center and TPY at the periphery) and 2TPY‐CBZ (N‐ethyl carbazole center and TPY at the periphery) was synthesized. The molecules show reverse saturable absorption (RSA) which is consistent with two‐photon absorption (2PA) associated with excited‐state absorption (ESA) when excited using a 532 nm laser beam. The molecules 2TPA‐TPY and 2TPY‐TPA possess extremely low limiting thresholds of 1.73 and 2.68 J cm−2, respectively. An organic light‐emitting diode (OLED) fabricated from 2TPA‐TPY exhibits green emission with a maximum luminance of 207 cd m−2, a current efficiency (ηCE) of 1.51cd A−1, a maximum power efficiency (ηPmax) of 0.46 lm W−1 and an external quantum efficiency (ηEQE) of 0.48 % at 100 cd m−2.
