We synthesize and assemble Small molecules able to capture or emit in the visible and infrared light, in particular, polymers and transition metal complexes for the fabrication of electroluminescent devices.
A special attention is devoted to find out luminescent compounds with high quantum yields to be exploited as efficient emitters in OLEDs. Cyclometalated organic complexes of heavy metals -Pt(II) and Ir(III) in particular- together with Cu(I) organic and hybrid complexes are the major interests of our research activity and solid state molecular behaviour together with intermolecular interactions have been deeply studied for this type of compounds. We develop novel Pt complexes able to produce, in the solid state, highly luminescent supramolecular species (dimers, excimers, aggregates). By carefully designing the device structure and the layers’ compositions we produced bright and efficient devices having emissions in different spectral regions. More recently, our attention is focused on using in our applications biodegradable and easily recyclable materials, in the framework of Green Electronics
By carefully designing the device structure and the layers’ compositions we have prepared bright and efficient devices having emissions in different spectral regions:
molecules and nanostructures which show: i) turn-on fluorescence recognition mechanisms in the presence of toxic or critical metabolic ions ii) turn on fluorescence upon recognition of G-quadruplex structures of DNA and iii) turn on fluorescence upon intracellular delivery.
