 Photochromic switches that can transmit information quickly have become increasingly popular in material science over the past few decades. While some photochromic materials can switch in under 100 of nanoseconds using other chromophores like spiroprants, achieving this speed with azobenzines remains challenging. This review discusses the latest advances in azobenzines, focusing on their structural features and how they relate to the thermal sister transase summarization process. Additionally, the kinetics and mechanisms behind the thermal backase summarization are explored as a way to achieve faster ASO derivatives.
