Synthesis and characterization of a nitrophenol disubstituted BODIPY halochromic probe

We report the synthesis and characterization of a (3,5)-nitrophenol substituted BODIPY dye bearing a clickable handle. The dye was initially studied in dichloromethane, where it absorbs and emits in the red (666 nm and 687 nm respectively). Stepwise…

Multifunctional benzonitrile derivatives with TADF and mechanofluorochromic properties and their application in OLEDs

In this study, we explore the solid-state photophysical properties of four donor-acceptor-donor' (D-A-D') fluorinated benzonitrile compounds, featuring combinations of phenoxazine and carbazole donor units. We have previously shown that these…

Advanced X-ray techniques to study the alteration of pigments in paintings

Abstract The application of X-ray methods (using conventional sources or synchrotron radiation) for investigating degradation phenomena in paintings has significantly increased in the last two decades. This rise is due to their ability to provide…

Oxidative electrofluorochromism of rhodamine in electropolymerized rhodamine-carbazole dyads

A rhodamine-carbazole dyad has been synthesized and electropolymerized to generate thin films. The spectroelectrochemical properties of the resulting polymer are investigated both in absorption and emission. We show that the luminescence of the…
