Description

1,8-Naphthalimide is an excellent fluorophore (fluorescent compound) with long emission wavelength band (400-600 nm), a large stokes shift, insensitive to pH and synthetic versatility. Triazole functional group has been used as binding sites for various metal ions in particular Zn(II), Cu(II) and Fe(III) metal ions. Based on naphthalimide as fluorophore and triazole as binding site, a new tripodal chemosensors has been designed and synthesized by copper catalyzed Huisgen Azide Alkyne cycloaddition reaction (known as click reaction). Its photophysical properties with various metal ions were investigated by fluorescence spectroscopy. Binding studies with various metal ions such as Zn(II), Cd(II) and Fe(III) by fluorescence and UV-Vis absorbance are under study in various solvent. Fluorescence is either enhanced or quenched on addition of these metal ions, which is attributed to PET (photo induced electron transfer) effect
