Abstract:
A photoswitchable supramolecular assembly can efficiently and reversibly switch on/off the luminescence of the [Ru(bpy)3]2+ center upon irradiation by light with different wavelengths in solution and the solid state. The assembly possesses reversible photoisomerization and a high Förster resonance energy transfer efficiency, and when used as an ink it can be reversibly and repeatedly erased and recovered by altering the wavelength of irradiation light.

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

2.4K
The absorption of UV–visible light by conjugated systems causes the promotion of an electron from the ground state to the excited state. Consequently, photochemical electrocyclic reactions proceed via the excited-state HOMO rather than the ground-state HOMO. Since the ground- and excited-state HOMOs have different symmetries, the stereochemical outcome of electrocyclic reactions depends on the mode of activation; i.e., thermal or photochemical.
