Zusammenfassung:
In time-resolved X-ray diffraction (TR-XRD), two different entities can be investigated as a function of time: the structural response function of a system upon photoexcitation and/or the population changes of short-living intermediates during the time course of a reaction. The time scales of these response functions might vary between hours and picoseconds, depending on the effects measured. By correlating the time evolution of structural changes with varying optical properties, it is possible to derive structure–function relationships in a time-dependent manner. The time-dependence of these relationships and the development of relevant methodologies is a major current interest in our group. Systems under investigation are organic materials with optical functionalities (molecular crystals, electron donor–acceptor systems) and solid state reactions (such as topochemical reactions).
