Spectroelectrochemistry of 9-aminoacridine tetracyanoquinodimethane conducting salt electrodes. Proton transport and cation intercalation solid state redox reactions

Guest–Host Complexes of TCNQ and TCNE with Cu3(1,3,5-benzenetricarboxylate)2

“…The shift to a higher potential compared to the monomeric form is ascribed to the stabilization of the TCNQ anion within the dimer. To the best of our knowledge, only a single report regarding the electrochemical investigation of a TCNQ dimer system has appeared in the literature, where the oxidation potential of (TCNQ) 2 2– inside a charge transfer complex was determined to be 0.26 V vs the saturated calomel electrode . The discrepancy between the redox potentials is attributed to the confinement of the TCNQ dimer inside the framework.…”

“…To the best of our knowledge, only a single report regarding the electrochemical investigation of a TCNQ dimer system has appeared in the literature, where the oxidation potential of (TCNQ) 2 2− inside a charge transfer complex was determined to be 0.26 V vs the saturated calomel electrode. 43 The discrepancy between the redox potentials is attributed to the confinement of the TCNQ dimer inside the framework. The large peak−peak separation of 0.49 V may be caused by the dissociation and re-formation of (TCNQ) 2 2− during the redox transformation.…”

The relationship between the electrochemistry and the crystallography of microcrystals. The case of TCNQ (7,7,8,8-tetracyanoquinodimethane)†‡

“…[20][21][22][23][24] By this means it has proved possible to study arrays of microcrystals that are spatially separate, free of grain boundaries, and free of significant IR drop. [25][26][27][28] Indeed, even compounds known to be electronically and ionically poorly conducting have yielded well-defined electrochemical responses. [29][30][31][32] In most compounds studied by this method, the electrochemical responses have been attributed to reactions on the surfaces of the microcrystals.…”

Is 9-acridinamine anion a dispersion-bound anion?

“…1͒. [1][2][3] Its relatively high quantum yield for fluorescence causes 9-AA to be used as a fluorescent probe in biologically important systems. 4 -11 Moreover, 9-AA and its derivatives possess a quite broad spectrum of biological activity including bacteriostatic, tranquilizing, analeptic, and antihistaminic behavior.…”
