Photoswitchable organocatalysis: using light to modulate the catalytic activities of N-heterocyclic carbenes.
TL;DR: The imidazolium species catalyzed transesterifications as well as amidations in a manner similar to those of previously reported N-heterocyclic carbene precatalysts, thus demonstrating a rare example of a photoswitchable catalyst that operates via photomodulation of its electronic structure.

Photoswitchable NHC-promoted ring-opening polymerizations
TL;DR: The UV-induced photocyclization of a dithienylethene-annulated N-heterocyclic carbene precatalyst enabled photoswitchable ring-opening polymerizations of ε-caprolactone and δ-valerolactone, however UV irradiation attenuated the reaction rate.

TL;DR: A rare example of steric stabilization of iron oxide (IO) nanoparticles (NPs) grafted with poly(2-acrylamido-2-methylpropanesulfonate-co-acrylic acid) (poly(AMPS- co-AA)) that not only display colloidal stability in standard American Petroleum Institute (API) brine but also resist undesirable adsorption on silica surfaces.

Photoswitchable Metal-Mediated Catalysis: Remotely Tuned Alkene and Alkyne Hydroborations
TL;DR: In this paper, a photochromic dithienylethene-annulated N-heterocyclic carbene (NHC)-Rh(I) complex was synthesized and found to undergo reversible electrocyclic ring closure upon alternate exposure to UV (λirr 313 nm) and visible (λ irr >500 nm) radiation.
