N4-Macrocyclic Metal Complexes

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. Metal complexes of N -ligands, such as porphyrins and phthalocyanines, are 4 widely studied due to their numerous physico-chemical properties and the great variety of their applications in many elds. For example, metalloporphyrins are usedasbiomimeticmodelsforstudyingseveralbiologicalredoxprocesses,inp- ticular for molecular oxygen transport and catalytic activation to mimic monoo- genase enzymes of the cytochrome P450. They are also well known as ef cient catalysts for oxidative degradation of various types of pollutants (organohalides, for example) and residual wastes. The high stability of metallophthalocyanines makes them suitable for applications in various elds such as catalysis (for - ample, the MEROX process for the sweetening of oils), electrocatalysis (air batteries and fuel cells), dye stuffs, coloring for plastics and metal surfaces, sensor applications, chromatographic detectors, photoconducting agents, etc. Both these families of complexes are now also used for photobiology and photodynamic cancer therapy, electrochemical removal of organic wastes, display devices, el- trochromism, electroluminescence, molecular metals, and nonlinear optical - plications. Additionally, the intrinsic diversity and selectivity of axial ligation of these macrocycles confer to them formidable challenging potential uses as electrochemical-sensing devices for several elds of application in analytical, electro-, and spectrophotochemistry. The rich and reversible redox chemistry of metalloporphyrins and met- lophthalocyanines is the key factor that allows them to serve as mediators in many electron transfer reactions. Since the 1970s and more importantly in recent years, numerous reports have demonstrated that these complexes can be successfully used as electrocatalysts for a great variety of electrochemical reactions

The book offers insight into applications and developments of N4 macrocycles complexes in biomimetic electrocatalysis, electroanalysis and energy storage. Chapters are devoted to (i) the chemistry, electronic and electrochemical properties of porphyrin and phthalocyanines and their applications in analytical, photoelectrochemical and energy storage molecular devices, (ii) the use of electropolymerized porphyrins, phthalocyanines and related complexes as electrocatalysts for the activation and the detection of a wide variety of environmentally polluting and biologically relevant molecules, and (iii) the structural, theoretical and spectral characterisation of various organisations and assemblies of porphyrins and related complexes. The exploration of these fields of research is now intensely stimulating the significant developments in molecular devices and intelligent organized materials for sensor science and technology.
