Abstract Colorless polyimide (CPI) is one of the most heat-resistant polymers. It has been widely used in many fields such as microelectronics and photoelectric fabrications, because it integrates the advantages of traditional aromatic polyimide (PI) films and common polymer optical films. This review summarizes the latest research and development of CPI films, including synthesis, properties and applications. In particular, the applications of CPI films in optoelectrical devices such as flexible thin film solar cells, advanced flexible display devices, flexible printed circuit boards, flexible terahertz sensors and smart windows are discussed.
