Complexation through the CT mechanism enables a long list of applications including studying binding mechanisms of pharmaceutical receptors, studying the pharmacodynamics and thermodynamics of molecules, and anti-inflammatory, antitumor, and antimicrobial studies [ [48] , [49] , [50] , [51] , [52] , [53] , [54] , [55] , [56] , [57] , [58] , [59] , [60] , [61] , [62] , [63] , [64] , [65] , [66] ]. Given the constant increase in the number and types of applications involvin...…”

Charge-transfer chemistry of azithromycin, the antibiotic used worldwide to treat the coronavirus disease (COVID-19). Part II: Complexation with several π-acceptors (PA, CLA, CHL)

“…A great deal of research has been dedicated to CT interactions due to their wide range of applications in the fields of chemistry, biology, physics, biochemistry, medicine, pharmacology, material science, and industrial technology [ [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] ]. Specifically, in the pharmacology and biochemistry fields, CT interactions contribute to the study of antimicrobial, antitumorigenic, and anti-inflammatory agents, binding mechanisms of pharmaceutical receptors, the thermodynamics and pharmacodynamics of clinical candidate compounds, DNA binding, enzymatic reactions, drug delivery, and quantitively characterizing pharmaceuticals [ [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] ]. In the fields of material engineering and technology, CT interactions facilitate the development and optimization of solar energy storage devices, organic solar cells, organic semiconductors, electrical conductors, biosensors, optoelectronics, non-linear optical materials, optical communication, photocatalysts, dendrimers, and several other magnetic, optical, and electrical technologies [ [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] , [55] , [56] , [57] , [58] , [59] ,…”

“…1b ). PA is a strong organic acid and the most frequently used acceptor investigated in CT interactions [ 23 , 32 , 44 , 53 , 105 , 116 , 117 , 125 , [143] , [144] , [145] , [146] , [147] , [148] , [149] , [150] , [151] , [152] , [153] , [154] , [155] , [156] , [157] , [158] , [159] , [160] , [161] , [162] , [163] ]. CLA and CHL are interesting from a biological perspective as benzoquinone derivatives.…”

Charge Transfer Complexes of Ketotifen with 2,3-Dichloro-5,6-dicyano-p-benzoquinone and 7,7,8,8-Tetracyanoquodimethane: Spectroscopic Characterization Studies

“…The CT mechanism was first discovered by Mullikan [ 3 ] and later described by Foster [ 4 ]. The formation of a hydrogen bond between the donor and the acceptor plays an important role in the formation of CT complexes, and these bonds determine the stability [ 5 , 6 ].…”
