Valency‐Controlled Multiphotochromism: Gated Switching and Photoswitchable Lewis Superacidity at Silicon

Angewandte Chemie, EarlyView.
Multiphotochromic switching is controlled by silicon valency in a diarylethene‐based molecular architecture. Lewis base coordination gates electronic communication between the photochromic units, thereby enabling selective access to distinct switching states.

Molecular Mobility of N‐Acetylgalactosamine‐Modified Cyclodextrins on a Polyrotaxane for Highly Efficient Liver Targeting of Antibody Chimeras and Genome‐Editing Ribonucleoproteins

Advanced Science, EarlyView.
Monovalent N‐acetylgalactosamine (GalNAc)‐modified polyrotaxane enables efficient liver targeting by utilizing ligand mobility. The sliding and rotating cyclic components i.e., cyclodextrin in the polyrotaxane dynamically cluster GalNAc moieties, thereby mimicking trivalent interactions with asialoglycoprotein receptors.

A Crystalline and Thermally Stable Selenocysteine Selenenic Acid

Angewandte Chemie, EarlyView.
The long‐sought catalytic intermediate of selenoproteins, selenocysteine selenenic acid (Sec–SeOH), is isolated for the first time at ambient temperature. A bioinspired selenopeptide sequence encapsulated within a protective molecular cradle and an oxidant‐free route from selenenyl iodide (Sec–SeI) enable the isolation of Sec–SeOH. Contrary to the long‐
