Summary: Photolithography is used to fabricate and control MOF-based heterostructured crystals, which can undergo a reversible structural transformation and emit blue or yellow-green light. This transformation enables the fabrication of erasable photonic barcodes. The heterostructure interface exhibits a photomechanical response that is fast, reversible and durable, even at high temperatures, making it promising for photoactuation. This work could inspire the development of intelligent MOF-based heterostructures for photonic applications.

Summary: This work presents a photoactivated organic room-temperature phosphorescence material, which utilizes triplet-to-singlet Forster-resonance energy transfer (TS-FRET) inhibited by visible-light stimulation. By doping a stable phosphorescence energy donor and a visible light-sensitive fluorescent dye into a polymer matrix, an amorphous organic RTP system is constructed. The phosphorescence intensity of the energy donor increases upon irradiation with visible light due to the photodegradation of the energy acceptor.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
