Congratulations to Bea Jones whose work on light-responsive liquid crystals has been published in JACS! In this collaboration with Imperial College, London (Matthew Fuchter and Jake Greenfield), we use arylazopyrazole surfactants to form lyotropic liquid crystals which show a hexagonal-to-cubic phase change on irradiation with UV light. This forms a structural continuity in the phase, which we use to control gas diffusion using light.
