Organic Chemistry of Photography
By Shinsaku Fujita.
Springer Verlag,
Heidelberg 2004.
587 pp., hardcover
E 181.85.—ISBN
3-540-20988-3
The stated aim of the author is to present the chemical fundamentals of photography from the viewpoint of organic
chemistry, thus filling a gap in the existing literature on photographic materials
and processes. The book is based on lectures given at the Kyoto Institute of
Technology, and draws on the authors
many years of experience in research
and development at the Fujifilm company.
The two introductory sections of the
book, which occupy 135 pages, describe
in great detail the multilayer structure
of photographic films and photographic
papers, with particular emphasis on the
crystal structures and the chemical and
photochemical properties of silver halides. At this stage, the author also
gives a concise and lucid introduction
to the principles of color photography.
This provides the nonspecialist reader
with a quick overview of the essential
points, whereas experts in the area of
photography can skip these two sections.
The three following sections are
mainly intended for specialists. Under
the headings “Chromogenic Photography”, “Diffusion Transfer Photography”, and “Dye Bleach Photography”,
the author gives a systematic description
Angew. Chem. Int. Ed. 2005, 44, 2629 – 2630
of the great number and variety of
organic compounds that are used in the
different variants of color photography.
As can be seen from these headings,
the organization of the book is firmly
based on the central concepts and techniques of photography. The individual
chapters are also structured in terms of
photographic and phototechnological
aspects, and accordingly the systematic
framework is built around words such
as developer, filter, activator, sensitizer,
inhibitor, etc. This organization of the
material is closely interwoven with the
conceptual structure of organic chemistry, which is based on classes of compounds and reactions, and therefore
that aspect is also reflected in the presentation. Chapters 8 and 21 of the
above three sections are especially
impressive because of the wealth of
examples of chemical compounds, with
detailed information about their structures and properties. The chapters
describe and discuss many methods for
the synthesis of compounds that are
important in photography, and the
mechanisms by which such compounds
work are explained, sometimes in
minute detail. Readers will be especially
impressed by the structural formulas in
the text, created by software that the
author has developed himself; as well
as showing the molecular structure
very clearly, they also give complete
information about functional groups,
substituents, counterions, etc. However,
as the numbering of the formulas
begins anew at the start of each chapter,
some of them are repeated unnecessarily. That could have been avoided by
using a continuous numbering system
throughout the book. A similar comment applies to the literature references,
as there is a list at the end of every one
of the 212 chapters. (Incidentally, the
chapters are numbered consecutively
throughout the five sections of the
book.) Apart from these minor cosmetic
shortcomings and a very small number
of printing errors, a first reading of the
book revealed no serious faults.
This book will serve as a good reference source for everyone whose work is
concerned with the chemistry of photography, or who wishes to get an overview
of the subject. For teachers of organic
chemistry, it is an interesting resource
from which they may take student exerwww.angewandte.org
cises on various parts of the discipline,
or which may suggest laboratory syntheses for practical work. Despite the rapid
onward march of digital photography,
the technology described in this book
will not become obsolete for a very
long time, and therefore the book
should find a firm place not only in the
libraries of university departments and
industrial laboratories, but also in
many private bookshelves.

Synthetic Multivalent Molecules
Concepts and Biomedical Applications. By Seok-Ki

Nature uses multivalent arrangements
of ligands to achieve affinity and selectivity for the corresponding receptors.
This fact is of crucial importance in
many biological processes, such as
recruitment of leukocytes during inflammation, cancer progression and metastasis, embryogenesis, etc. These examples
have inspired scientists to develop new
multivalent synthetic systems, to understand and intervene in biological processes at the molecular level. A lot of
work related to this topic has been published during the past few decades, and
nowadays there is a huge amount of
information accessible to the scientific
community. The interest in this topic
and the large amount of available information justifies the appearance of a
book that aims to collect all this information in an organized manner.
