Naphthalimide Dye

Six-membered diaza ring of Cinnoline have been fused on Naphthalimide dye to give donor–acceptor system called CinNapht. These red shifted fluorophore, that can be synthetised in gram scale, exhibits a large Stoke Shift and quantum yield up to 0.33. It is also caracterized by strong solvatochromic effect for green to red emission as well and can be used for bio-imaging
