Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.Herein, the topochemical transformation of cobalt‐based layered hydroxides into nanocomposites is investigated using advanced real‐time characterization techniques combined with thermogravimetric analysis. The study reveals how interlayer carboxylic acids direct the transformation pathway, highlighting the role of carbon content and anion length. These

Mechanochemical Regulation of a Photochemical Reaction [PDF]
, 2018 We introduce the concept of mechanochemically gated photoswitching. Mechanical regulation of a photochemical reaction is exemplified using a newly designed mechanophore based on a cyclopentadiene–maleimide Diels–Alder adduct.
