title: Investigating new photoactive ferroelectrics using dynamic X-ray diffraction techniques - data

description: This dataset contains crystallographic information files (CIFs) for the single-crystal X-ray data detailed in the PhD thesis "Investigating new photoactive ferroelectrics using dynamic X-ray diffraction techniques", by Joshua J. Morris and submitted for examination in 2024. Compounds [1] to [5] were designed and investigated for their potential to display photoinduced energy generation. All materials are hybrid organic-inorganic crystalline solids that are display interesting switching properties in response to the application of electric field, temperature and light and this thesis details their synthesis, crystallization and characterisation by a variety of solid-state analytical techniques including novel in-situ single-crystal X-ray diffraction measurements under the application of high electric field and visible / IR light irradiation (photocrystallographic studies). Intermediates [7a], [8a], [9a] and [10a] were synthesized according to a literature procedure and single crystal X-ray structures collected at 150K were collected to characterize the products.
