Abstract: International audience; Six-membered-diaza ring of Cinnoline has been fused on Naphthalimide dye to give a donor-acceptor system called CinNapht. This red shifted fluorophore, that can be synthetised in gram scale, exhibits a large Stoke Shift and a fluorescence quantum yield up to 0.33. It is also characterized by a strong solvatochromic effect from green to red emission as well and can be used for bioimaging.
