The field of optoelectronic polymers has continuously expanded in the past two decades because of their innovative applications in a variety of technologies in optoelectronic, photonic and energy research. Groups across the world are still looking into the fundamentals, as well as their applications, which remain to be fully understood and envisioned. This is the first book on the topic for researchers who are entering the field, highlighting the remarkable basic science and technological potential of this class of materials. Chapters will focus on the fundamental concepts as well as up-and-coming research into the applications of these polymers. Chapters will look at topics such as pure organic phosphorescence and external stimuli-responsive luminescent materials that are not covered in other books.
