Summary: Photochromic sodalites have a wide range of potential applications, such as UV indexing and X-ray imaging, but further optimization is needed. UV indexing can be improved by adjusting the activation energy of coloration from 300 to 410 nm through replacing sulfur with selenium. By combining this method with others, the excitation threshold and photochromism color can be independently tuned. The absorption maxima range can be expanded to cover almost the entire visible spectrum. Mixing low-cost and easy-to-synthesize sodalites further expands the color possibilities and enables the development of a unique sodalite mix for quantifying two types of UV radiation doses simultaneously. Finally, highly tuned sodalites show promising response to X-rays, producing clear images with lower radiation doses than classic photochromic sodalite.

Summary: The stability-related issues of perovskite precursor inks, films, device structures, and interdependence have not been explored sufficiently. In this study, a ionic-liquid polymer (poly[Se-MI][BF4]) was designed to stabilize the entire device fabrication process. The functional moieties of carbonyl (C=O), selenium (Se+), and tetrafluoroborate (BF4-) ions in the polymer effectively stabilized the lead polyhalide colloids and perovskite precursor inks. The poly[Se-MI][BF4] also suppressed the dissociation and migration of iodine (I-) in perovskite films with the help of anchored selenium ions and passivated defects by BF4-. High efficiencies of 25.10% and 20.85% were achieved by a 0.062-cm(2) device and 15.39-cm(2) module, respectively, with over 90% retention of initial efficiency after 2200 hours of operation.

Summary: The development of dynamic anticounterfeiting inks with time-dependent photochromism and photoluminescence characteristics has gained significant interest in advanced encryption systems. These inks have various applications, such as tracking UV rays and gas leakage, as well as quality monitoring. In this study, colloidal nanoparticles were synthesized using semi-continuous copolymerization and then incorporated with a photochromic compound to prepare the dynamic inks. The optical properties of the inks depended on the chain polarity and flexibility of the nanoparticles, and their time-dependent features were attributed to the gradual transformation of the photochromic compound under visible light induction. These innovative inks have achieved unprecedented advances in the field of information security and encryption.

Summary: Smart polymers with different responses to induced stimuli have attracted much attention. Polymers with fluorescent properties have potential applications in fluorescence chemosensors, optoelectronics, molecular thermometers, organic light-emitting diodes, molecular imaging, storage data security, drug delivery carriers, and encryption. Fluorescence resonance energy transfer (FRET) is an advanced optical mechanism that can be controlled by the swelling, aggregation, or collapsing of smart polymers, thereby affecting the spatial distance and efficiency. This review article focuses on the application of FRET in smart polymers for imaging and detection, based on the modulation of FRET efficiency by the smart polymer response to various stimuli including temperature, pH, light, solvent, glucose, and mechanical force.
