About the book
The use of dyes and pigments is narrowly associated with everyday life. Since ancient times, people have been using various types of dyes and pigments for both aesthetic and practical applications. Typically, the coloration of various materials e.g. textiles, clay, plastics, etc. has been their main purpose. Yet, the scope of contemporary dyes and pigments has become significantly broader and there is constant interest in new products fulfilling numerous requirements parallel to their ability to act as colorants. This trend has led to the development of functional dyes.
In recent years, novel dyes and pigments with hi-tech applications have been developed and there is a continuous demand for new products with better properties and/or broader application scope. Of particular interest is the development of dyes and pigments with environment-responsive aptitudes i.e. products that can undergo some structural modification as a result of external stimuli e.g. light, heat, pressure, pH-changes, etc. These stimuli-responsive functional dyes have in turn found application in sensor technologies, optical data storage, molecular switches, etc. Acknowledging these facts, this book aims to cover current state-of-the-art research and development in the remarkably important area of environment-responsive (multi)functional dyes and pigments.
