Visible-emitting hybrid sol–gel materials comprising lanthanide ions: thin film behaviour and potential use as phosphors for solid-state lighting

The synthesis and characterization, as well as the film-forming and luminescent properties of four visible-emitting hybrid organic-inorganic sol-gel materials are reported. They show thermal stability up to 165°C. Deposition conditions were…

Alternated bimetallic [Ru–M] (M = Fe2+, Zn2+) coordination polymers based on [Ru(bpy)3]2+units connected to bis-terpyridine ligands: synthesis, electrochemistry and photophysics in solution or in thin film on electrodes

Two alternated bimetallic Ru–Fe and Ru–Zn coordination polymers, [{RuII(bpy)2(L2)MII}n]4n+ (M = Fe2+, Zn2+), were synthesized using the [Ru(bpy)2(L2)]2+ (bpy = 2,2′ bipyridine) complex as a building block, in which L2 is a bipyridine ligand…

Multichromophoric sugar for fluorescence photoswitching

A multichromophoric glucopyranoside 2 bearing three dicyanomethylenepyran (DCM) fluorophores and one diarylethene (DAE) photochrome has been prepared by Cu(I)-catalyzed alkyne-azide cycloaddition reaction. The fluorescence of 2 was switched off upon…
