Electrochemical Behavior of C60−p-Tert-butylcalix[8]arene Inclusion Complex Film in Mixed Acetonitrile and Water

Abstract

Electrochemical behavior of C 60 ¹p-tert-butylcalix[8]arene inclusion complex film has been studied by cyclic voltammetry. One pair of stable reduction/reoxidation peaks was obtained in a mixed solvent of acetonitrile and water (3:1 v/v) containing tetra-n-butylammonium perchlorate as the supporting electrolyte. The process is a two-electron transfer reaction.

Supramolecular Incorporation of Fullerenes on Gold Surfaces: Comparison of C60 Incorporation by Self-Assembled Monolayers of Different Calix[n]arene (n = 4, 6, 8) Derivatives

“…30 In another report, one pair of stable reduction/reoxidation peaks was obtained for the C 60 -calix [8]arene inclusion complex in a mixed acetonitrile and water solution. 15 The peak currents of SAM-modified electrodes with 5 after incubation in the C 60 solution were reduced gradually upon successive scans, indicating the dissolution of C 60 and/or the desorption of the monolayers. The electrochemical behavior of the C 60 -calix [8]arene complexmodified electrodes is dependent on the film preparation method.…”

Study on Preferential Solvation of Water by Electrochemical Method

“…However, the effect of water always is ubiquitous but often overlooked as a background environment in the water and organic solvent. In fact, the preferential solvation of water plays an important role in electrochemical behavior of solute , hydrogen evolution reaction , double layer capacitance , the process of electronic transfer . Exploring preferential solvation of water by electrochemical methods would provide new insights into the effect of water in the field of electrochemical research.…”

Electrochemical and Structural Studies on Microcrystals of the (C60)x(CTV) Inclusion Complexes (x = 1, 1.5; CTV = cyclotriveratrylene)

“…Fullerene C 60 forms a wide range of supramolecular complexes with a variety of container molecules including azacrown ethers, γ-cyclodextrin, , calixarenes, − and cyclotriveratrylene (CTV). , These complexes are of interest in material science, biological applications, , and in separation science. ,,, Recently, both solid-state and solution-phase electrochemical studies of these kinds of complexes ,− have been undertaken to explore the impact of the C 60 redox level on the chemistry. In the present investigation, further structural details on the (C 60 ) 1.5 (CTV) complex are elucidated by X-ray crystallography, and electrochemical studies on microcrystals of supramolecular complexes of fullerene, (C 60 ) x (CTV) ( x = 1, 1.5) complexes adhered to electrode surfaces, have been undertaken in order to explore the relationship between electrochemical behavior and the structure of host−guest complexes.…”
