“…Thereafter, the concept of CT interactions was widely disseminated by Roy Foster. Foster described the importance of CT complexes in several physicochemical processes such as paramagnetism, semiconductivity, photoconductivity, and in biological processes [ [1] , [2] , [3] , [4] , [5] , [6] ]. CT interactions have been used in dendrimers, photocatalysts, optical communication, non-linear optical materials, optoelectronics, organic semiconductors, biosensors, electrical conductors, organic semiconductors, organic solar cells, and solar energy storage devices [ [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] , [46] , [47] ].…”
