Highly Efficient Photoswitch in Diarylethene-Based Molecular Junctions.
Journal of the American Chemical Society, 2020 Thin layers of diarylethene oligomers (oligo(DAE)) were deposited by electrochemical reduction of a diazonium salt on glassy carbon and gold electrodes. The layers were fully characterized using electrochemistry, XPS, and AFM, and switching between open ...

First direct evidence of N-heterocyclic carbene in BMIm acetate ionic liquid. An electrochemical and chemical study on the role of temperature [PDF]
, 2017 Cyclic voltammetry provides the first direct evidence of N-heterocyclic carbene (NHC) presence in neat 1-‐butyl-3-methylimidazolium acetate ionic liquid (BMImAcO) at 120°C. The NHC existence, proved by its oxidation current in cyclic voltammetry, was

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.
