Abstract
Over the last three decades, the technology that makes it possible to follow chemical processes in the solid state in real time has grown enormously. These studies have important implications for the design of new functional materials for applications in optoelectronics and sensors. Light–matter interactions are of particular importance, and photocrystallography has proved to be an important tool for studying these interactions. In this technique, the three‐dimensional structures of light‐activated molecules, in their excited states, are determined using single‐crystal X‐ray crystallography. With advances in the design of high‐power lasers, pulsed LEDs and time‐gated X‐ray detectors, the increased availability of synchrotron facilities, and most recently, the development of XFELs, it is now possible to determine the structures of molecules with lifetimes ranging from minutes down to picoseconds, within a single crystal, using the photocrystallographic technique. This review discusses the procedures for conducting successful photocrystallographic studies and outlines the different methodologies that have been developed to study structures with specific lifetime ranges. The complexity of the methods required increases considerably as the lifetime of the excited state shortens. The discussion is supported by examples of successful photocrystallographic studies across a range of timescales and emphasises the importance of the use of complementary analytical techniques in order to understand the solid‐state processes fully.
