Photoswitchable fluorescent dyes for RESOLFT super-resolution microscopy [PDF]

open access: yes, 2023
Super-resolution fluorescence microscopy, which allows the resolution of features below the diffraction limit of light, has transformed our ability to investigate cellular processes on the nanoscale.

Halogen bonding stabilizes a cis-azobenzene derivative in the solid state: A crystallographic study [PDF]

open access: yes, 2017
Crystals of trans- and cis-isomers of a fluorinated azobenzene derivative have been prepared and characterized by single-crystal X-ray diffraction. The presence of F atoms on the aromatic core of the azobenzene increases the lifetime of the metastable ...

Synergistic Two‐Color Photochemical Polymer Network Formation and Lithography

open access: yesAngewandte Chemie, Volume 137, Issue 48, November 24, 2025.
Two photoswitches, able to respond to disparate wavelengths, are integrated into multi‐functional polymer architectures to form a photoresist that responds to curing upon irradiation with two distinct monochromatic colors of light, enabling two‐color lithography.

Phosphine-Catalyzed Annulations of Azomethine Imines: Allene-Dependent [3 + 2], [3 + 3], [4 + 3], and [3 + 2 + 3] Pathways [PDF]

open access: yes, 2011
In this paper we describe the phosphine-catalyzed [3 + 2], [3 + 3], [4 + 3], and [3 + 2 + 3] annulations of azomethine imines and allenoates. These processes mark the first use of azomethine imines in nucleophilic phosphine catalysis, producing ...
