Book Description
This is the second set of Handbook of Porphyrin Science.Porphyrins, phthalocyanines and their numerous analogues and derivatives are materials of tremendous importance in chemistry, materials science, physics, biology and medicine. They are the red color in blood (heme) and the green in leaves (chlorophyll); they are also excellent ligands that can coordinate with almost every metal in the Periodic Table. Grounded in natural systems, porphyrins are incredibly versatile and can be modified in many ways; each new modification yields derivatives, demonstrating new chemistry, physics and biology, with a vast array of medicinal and technical applications.As porphyrins are currently employed as platforms for study of theoretical principles and applications in a wide variety of fields, the Handbook of Porphyrin Science represents a timely ongoing series dealing in detail with the synthesis, chemistry, physicochemical and medical properties and applications of polypyrrole macrocycles. Professors Karl Kadish, Kevin Smith and Roger Guilard are internationally recognized experts in the research field of porphyrins, each having his own separate area of expertise in the field. Between them, they have published over 1500 peer-reviewed papers and edited more than three dozen books on diverse topics of porphyrins and phthalocyanines. In assembling the new volumes of this unique Handbook, they have selected and attracted the very best scientists in each sub-discipline as contributing authors.This Handbook will prove to be a modern authoritative treatise on the subject as it is a collection of up-to-date works by world-renowned experts in the field. Complete with hundreds of figures, tables and structural formulas, and thousands of literature citations, all researchers and graduate students in this field will find the Handbook of Porphyrin Science an essential, major reference source for many years to come.

Book Description
Phosphonium ionic liquids were utilized as novel reaction media in order to detect new chemistry for catalytic metalloporphyrins. This research involves two general areas: (1) EPR and ENDOR spectroscopic studies of metalloporphyrins in different hosts: ionic liquids, porous materials, and conventional molecular solvents; (2) catalytic reactivity and mechanism studies of metalloporphyrins in different hosts. Spectroscopic results indicate a distortion in geometry of copper porphyrins in ionic liquids, which shifts the spin density distribution within the molecule. Similar studies of iron porphyrins indicate that component ions from ionic liquids can bind to the metal centres of these catalytic molecules. Some ionic liquids were found to improve the reactivity of porphyrin catalysts in oxidation reactions due to their ability to solubilize all reaction components and to prevent aggregation of porphyrins. A porphyrin radical cation intermediate was detected in the oxidation reaction of 4-methoxythioanisole by iron meso-tetra(4-sulfonatophenyl)porphyrin.

Book Description
Porphyrins play a vital role in many biological functions including oxygen transport, electron transfer and catalyzing the incorporation of oxygen into other molecules. This current survey discusses the use of modern physical techniques to probe porphyrin structure and function. The authors review the data available through a particular technique and show what can be learned therefrom about the (electronic) structure and function of biologically important porphyrins. The techniques include magnetic circular dichroism, X-ray absorption fine structure (EXAFS) and Mössbauer spectroscopies. All contributors are well known in their respective fields, enjoying world-wide reputation.
