In this work, device-friendly solid films with color tunability are prepared by constructing Förster resonance energy transfer (FRET) platforms with chiral donors and achiral molecular switches in liquid crystal photonic capsules (LCPCs). These LCPCs exhibit photoswitchable CPL from initial blue emission to RGB trichromatic signals under UV irradiation due to the synergistic effect of energy and chirality transfer and show strong time dependence because of the different FRET efficiencies at each time node. Based on these phototunable CPL and time response characteristics, the concept oNature communications3005https://www.ebi.ac.uk/biostudies/studies/S-EPMC10212932biostudies-literaturePhoto-triggered full-color circularly polarized luminescence based on photonic capsules for multilevel information encryption.PMC10212932Kang WLin SGuo JLi QTang YBisoyi HKfalsePhoto-triggered full-color circularly polarized luminescence based on photonic capsules for multilevel information encryption.Materials with phototunable full-color circularly polarized luminescence (CPL) have a large storage density, high-security level, and enormous prospects in the field of information encryption and decryption.
