Abstract Due their multifaced applications, the access to organosulfur derivatives in an efficient and economical way is a challenge organic synthesis. In this context photochemistry photocatalysis play crucial role development of innovative (and selective) Carbon‐Sulphur bond formation processes. The present review aims collect most recent strategies achieve target under visible light driven c...

The movement of a liquid droplet on a flat surface functionalized with a photochromic azobenzene may be driven by the irradiation of spatially distinct areas of the drop with different UV and visible light fluxes to create a gradient in the surface tension. In order to better understand and control this phenomenon, we have measured the wetting characteristics of these surfaces for a variety of ...

Exploring routes to visible-light-driven rotary motors, the possibility of red-shifting the excitation wavelength of molecular motors by extension of the aromatic core is studied. Introducing a dibenzofluorenyl moiety in a standard molecular motor resulted in red-shifting of the absorption spectrum. UV/vis and 1H NMR spectroscopy showed that these motors could be isomerized with light of wavele...
