A novel N-substituted 4-methoxy-1,8-naphthalimideÂ (NAFTA 8) especially designed for fluorescent labeling ofÂ goldÂ nanoparticles has been synthesized. NAFTA 8 bears a long methylene chain at theÂ imideÂ N atom and has a terminal SH group, which enables its chemical binding toÂ goldÂ nanostructures. The longest wavelength absorption maximum of NAFTA 8 in chloroform is at 370Â nm, the fluorescent maximum is at 430Â nm and the fluorescent quantum yield is 0.95. The newly synthesized fluorophore is applied for functionalization ofÂ goldÂ nanoparticles with diameter 1.5Â Â±Â 0.5Â nm prepared through chemical reduction. The obtained Monolayer Protected Clusters are characterized by elemental analysis, TEM, XPS, FT-IR, absorption and fluorescence spectroscopy. The performed investigations provide evidence for the formation of chemical bond between the thiol ligand and theÂ goldÂ surface. They also show that the obtained metal/dielectric 3D structures are highly fluorescent.
