Photoactive chelating organic nanospheres as central platforms of bimodal hybrid nanoparticles

An innovative approach based on the combination of pre-formed nano-objects using photoactive chelating organic nano-platforms has been developed to elaborate hybrid functional nanoparticles. In this way, original “raspberry-like” structures made of…

One-photon excited luminescence of single gold particles diffusing in solution under pulsed illumination

Here we report on the visible luminescence of single gold nanospherical particles diffusing in water excited by a pulsed-laser at 488 nm. The signal studied by fluorescence correlation spectroscopy does not display the expected characteristics. The…

Decoupling Fluorescence and Photochromism in Bifunctional Azo Derivatives for Bulk Emissive Structures

Bifunctional molecules that combine independent pushpull fluorophores and azo photochromes have been synthesized to create fluorescent structures upon light-induced migration in neat thin films. Their photochromic and emissive properties have been…

Electrochromic and electrofluorochromic properties of a new boron dipyrromethene-ferrocene conjugate

A new boron dipyrromethene-ferrocene (BODIPY-Fc) conjugate with pentafluorophenyl as the meso substituent and two Fc termini was synthesized and its spectroscopic and electrochemical features were analysed. An intramolecular charge transfer from the…

Tunable double photochromism of a family of bis-DTE bipyridine ligands and their dipolar Zn complexes.

The photoinduced ring-closure/ring-opening reactions of a series of bis-dithienylethene derivatives, as free ligands and Zn(II)-complexes, are investigated by resorting to theoretical (time-dependent density functional theory) and kinetic analyses…
