Multidimensionally Programming Photoswitching via Orthogonal Covalent‐Noncovalent Chemistry for Dual‐Track Time‐Resolved Optical Encryption

Advanced Science, EarlyView.
A dual‐track time‐resolved encryption strategy with independent information display during photo‐bleaching and thermal‐recovery stages has been realized through multiple temporal encoding units derived from orthogonal covalent‐noncovalent programming of donor–acceptor Stenhouse adduct photoswitching.

Elucidating Liquid‐Phase Guest Transport Across MOF Single Crystals: Interplay of Adsorption, Desorption, and Intracrystalline Diffusion

Angewandte Chemie, EarlyView.
Guest transport across metal–organic framework (MOF) single crystals disentangles transport occurring through the micropores from contributions at grain boundaries. Even guest molecules with identical kinetic diameters show drastically different transport behavior arising from the distinct modes of adsorption. Neither pore clogging nor surface collapse

Metal-Ion Regulated Light-Free Z→E Isomerization of Azobenzene Glycomacrocycle. [PDF]

Chemistry
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.
