Prussian Blue (PB) {Fe4[Fe(CN)6)3] nH2O} is the First synthetic pigment discovered in 1704 by Disbatch. Prussian Blue (Ferric Ferrocyanide) is a mixed valance compound having Zeolite type structure. Prussian Blue is a prototype of a family of compounds {Metal Hexacyanoferrates, with general formula as AhMk[Fe(CN)6]l.mH2O; where h, k, l, m are stoichiometric numbers, A is Alkali metal cation and M is transition metal ion} having similar structures usually known as Prussian Blue Analogous. Various Prussian Blue Analogous can be manufactured by replacing the metal atoms by Co, Ni, Fe, etc. Although it contains carbon, it is classified as an Inorganic Material. Since its discovery, it is widely used for a variety of applications. An interesting feature of these compounds is that they resemble not only to redox organic polymers but also to Zeolites or intercalation materials.

Today, hundredes of dyes and pigments or even Inorganic materials are available. However, this particular pigment / compound / class of compound is of high interest, ever since from its discovery. It's because of particular structural, redox, spectroscopic, charge transfer and physico-chemical properties along with easy synthesis including by electrochemical means. This is the reason why it is termed as "EverGreen Pigment" by A. Ludi (Journal of Chemical Education 1981, 58, 1013). Recent interest in Prussian Blue (s) is for : (1) Electrochromic Applications (2) Catalysis (3) Sensors (4) Porous Material (5) Molecular Magnet (6) Photoinduced Magnetization (7) Colored Magnetic Thin Films (8) Photo-rechargable Battery Electrode (9) Nano-forms (such as Nanoparticles, Nanopillers, Nanowires, Ultra-thin films) and Nano-composites (such as Prussian Blue coated carbon nanotubes) (10) Battery electrodes and so on.

Via this book, it is thought to consolidate all important information and know-how available on Prussian Blue and its Analogous. This book is expected to serve as an important information source for Researchers, Scientists, Professors by providing them information about the current state-of-the-art in the field. It is also expected to stimulate interest in students, young researchers and new-commers to this field. Each book chapter / article is written by an expert in this field.

It is a cutting-edge interdisciplinary book specifically focused on Prussian Blue and its Analogous, and their fundamentals and technological applications. This book can be used as a Text book as well as a Reference book. This book is a valuable source for scientists, graduate students, researchers, and other professionals working / interested in Prussian Blue and its Analogous, Molecular Magnets, Electrochemistry, Nanoscience and Nanotechnology, Materials Science, Physics, and Chemistry.
