Electrochemistry of 2-dimethylaminoethanethiol SAM on gold electrode: Interaction with SWCNT-poly(m-aminobenzene sulphonic acid), electric field-induced protonation-deprotonation, and surface pKa.

Vol. 11(6), pp 1292 - 12961388-2481http://hdl.handle.net/10204/3584Copyright: 2009 ElsevierElectrochemical behaviour of self-assembled monolayer of 2-dimethylaminoethanethiol (DMAET) on gold electrode, with and without integration with SWCNT-poly(m-aminobenzene sulphonic acid) (SWCNT-PABS) has been probed. It is proved that the so-called electric field induced protonation-deprotonation process, hitherto observed for the -COOH terminated SAMs, is also observed for the -N(H)+(CH3)2 terminated. The surface pKa of DMAET was estimated as 7.6, smaller than its solution pKa of 10.8. It is also shown that SWCNT-PABS is irreversibly attached to the DMAET SAM.enSelf-assembled monolayerProtonation-deprotonationSurface pKaCyclic voltammetryElectrochemical impedance spectroscopyElectrochemistry Communications2-dimethylaminoethanethiolGold electrodeSWCNT-poly(m-aminobenzene sulphonic acid)Electric field-induced protonation-deprotonationArticlePillay, J., Agboola, B., & Ozoemena, K.
