Book Description
Cyclic voltammetric measurements of adsorbed Fe- and Co-tetrasulfonated phthalocyanine (TsPc) and Co-phthalocyanine (Pc) have been carried out on ordinary pyrolytic graphite and silver electrodes at different solution pH ranging from 1 to 13. Many voltammetry peaks were found to be pH dependent with a slope of -59 mV/unit pH. In some instances this dependence was observed in alkaline or acid solutions only. Explanations for the various voltammetry peaks and their pH dependence are discussed. The influence of dioxygen and its reduction have also been examined. Keywords: Macrocycles, Tetrasulfonated phalocyanines, Adsorption layers, Electrochemical properties, Voltammetry.

Book Description
Adsorbed layers of iron tetrasulfonated phthalocyanine have been examined using cyclic voltammetry on the silver single crystal low index surface: (100), (110), and (111). The peak potentials and charge under the voltammetry peaks show some dependence on the crystal planes. The effects of the underpotential deposition of lead on the adsorbed macrocycle have also been examined on the silver single crystal electrode. The lead can be underpotential deposited on the silver directly through a pre-adsorbed macrocycle layer without desorbing the macrocycle. The data are explained in terms of a model for the adsorbed macrocycle which has the plane of the ligand perpendicular to the electrode surface.

Book Description
In response to significant developments in sensor science and technology, this book offers insight into the various extended applications and developments of N4 macrocycle complexes in biomimetic electrocatalysis. Chapters are devoted to the chemistry, electronic and electrochemical properties of porphyrin- based polymetallated supramolecular redox catalysts and their applications in analytical and photoelectrochemical molecular devices; the use of porphyrins, phthalocyanines and related complexes as electrocatalysts for the detection of a wide variety of environmentally polluting and biologically relevant molecules; and the use of electropolymerized metalloporphyrin and metallophthalocyanine films as powerful materials for analytical tools, especially for sensing biologically relevant species.

Book Description
The purpose of this monograph is to provide a summary for those who are active in the field of phthalocyanine research. This volume allows the reader to quickly-and at a reasonable cost-determine what is being accomplished so that he may plan his own research programs. It covers such topics as synthesis, reactions, inks, energy systems, coatings, toners, and electrophotographic plates and developers, just to name a few. Packed with over 40 structural drawings of phthalocyanine molecules, this one-of-a-kind reference provides the necessary description and visualization to stimulate further research. This work is an indispensable resource for researchers and practitioners, both novice and experienced, in the field of phthalocyanine science and technology.
