Photodynamic Control-Mediated Holographic Composites In article number 2100363, Jae-Won Ka and co-workers propose new holographic composites with photodynamic control, composed of photosensitizers, singlet oxygen receptors, polymeric binders. Upon laser irradiation, photoexcited sensitizers generate oxygens, which can be detected by their receptors structural changes. Such changes within the could cause permanent interference light-induced transmittance gradients, enabling recordings.
