Title: | Multiple Redox-Active Sites in Copper Dipyrromethene-Corrole Self-Assembled Monolayers Deposited onto Gold Electrodes | Authors: | Grabowska, Iwona MAES, Wouter Ngo, Thien Huynh Rohand, Taoufik Dehaen, Wim Radecki, Jerzy Radecka, Hanna |
Issue Date: | 2014 | Source: | INTERNATIONAL JOURNAL OF ELECTROCHEMICAL SCIENCE, 9 (3), p. 1232-1249 | Abstract: | In this work, both separate dipyrromethene and copper corrole derivatives and a specifically designed copper corrole-dipyrromethene conjugate were applied for gold electrode modification. The various oligopyrrole materials were used for copper complexation toward the preparation of different types of electroactive self-assembling monolayers (SAMs): (i) a copper dipyrromethene (Cu-DPM) SAM, (ii) a copper corrole (Cu-COR) SAM, and (iii) a copper dipyrromethene-copper corrole conjugate (Cu-DPM- Cu-COR) SAM. The SAMs incorporating the single Cu sites as well as, two Cu sites located in one molecule, one over another, were characterized by cyclic voltammetry, Osteryoung square-wave voltammetry and electrochemical impedance spectroscopy. | Notes: | Grabowska, I (reprint author),Polish Acad Sci, Inst Anim Reprod & Food Res, Tuwima 10, PL-10748 Olsztyn, Poland. h.radecka@pan.olsztyn.pl | Keywords: | dipyrromethene; corrole; self-assembled monolayers; copper complexation; mono- and multi-redox sites | Document URI: | http://hdl.handle.net/1942/16747 | ISI #: | 000331194200016 | Rights: | © 2014 by ESG (www.electrochemsci.org). | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2015 |
