Focusing on how conjugated polymers can be designed and made for use in efficient organic electronic devices, this book covers the tools for future development of more environmentally and economically friendly devices. Including examples of interdisciplinary science, it exemplifies how chemists and physicists work together to enable the design and synthesis of high-performance material in devices, allowing polymer-based electronic devices to become viable commercial products. It provides the main classes of conjugated polymers and their applications in organic electronic devices such as transistors, light-emitting diodes, and solar cells, making this a comprehensive introduction. This complete guide includes the methods for making conjugated polymers, the properties and specific structures that make them suitable for use, and how their synthesis can be optimised to improve device performance. Written by experts in the field, this is the ideal guide for researchers and practitioners across materials science, physics, chemistry, and electrical engineering.
