Scientists in such fields as mathematics, physics, chemistry, biochemistry, biology, and medicine are currently involved in investigations of porphyrins and their numerous analogues and derivatives. Porphyrins are being used as platforms for the study of theoretical principles, as catalysts, as drugs, as electronic devices, and as spectroscopic probes in biology and medicine. The need for an up-to-date and authoritative treatise on the porphyrin system has met with universal acclaim amongst scientists and investigators.

The Porphyrin Handbook, Volume 18: Multiporphyrins, Multiphthalocyanines and Arrays provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into five chapters, this volume begins with an overview of the results obtained in the research concerning the properties and formation of a class of metal phthalocyanine derivatives containing of two macrocyclic units. This text then examines the luminescence and photophysical data of multiporphyrin systems in which the chromophore centers are held together by weak, medium, or strong bonding interactions. Other chapters consider the intensive electronic absorption and circular dichroism properties of chiral phthalocyanines. This book discusses as well the chemistry porphyrin and corrin systems. The final chapter deals with geoporphyrins or sedimentary porphyrins, which are the most abundant porphyrin derivatives on earth. This book is a valuable resource for research scientists, engineers, and clinicians.

The Porphyrin Handbook, Volume 16: Phthalocyanines: Spectroscopic and Electrochemical Characterization provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into five chapters, this volume begins with an overview of the photophysical properties of phthalocyanines that are important in relation to photosensitizers in photodynamic therapy, photoconductor, solar cells, and artificial photosynthesis. This text then describe how the data obtained from magnetic circular dichroism spectroscopy has provided the critical information required to describe the excited and ground state degeneracies of main group metallophthalocyanines complexes. Other chapters consider the electrocatalysis by electrodes modified with phthalocyanine sensors and complexes. This book discusses as well the properties of phthalocyanines and of their complexes. The final chapter deals with the experiments with organic pigment thin films. This book is a valuable resource for research scientists, engineers, and clinicians.

Announcing the sequel to the first ten volumes of The Porphyrin Handbook, which provided an authoritative treatise on the porphryin system and dealt in fine detail with the synthesis, chemistry, spectroscopy, and applications of porphyrins. The ten latest volumes 11-20 address those major disciplinary areas not covered in the first, including biology and medical implications of porphyrin systems, the biosynthesis of porphyrins, chlorophylls and vitamin B12. Other areas include the multitude of genetically transmitted and drug induced diseases associated with errors in heme metabolism, the transformations of hemes into bile pigments, the organic syntheses of bilins, very recent work on phytochrome, and the pathways of degradation of chlorophyll in senescent plants. In addition, volumes 11-20 address every aspect of synthesis, chemistry, structure and spectroscopy of phthalocyanines which will appeal to scientists in fields ranging from mathematics through physics, chemistry and biochemistry, to biology and medicine. . By the same Editors as the successful first Porphyrin Handbook, published in 2000. . Consists of 61 chapters written by internationally recognized experts. . Clear, concise, and uniform presentation with many hundreds of figures, tables and structural formulae. Including volume indices and cumulative index.
