Abstract

Some indolizines with phenanthroline skeleton derivatives have been investigated using steady state absorption, emission and time resolved fluorescence techniques. The effects of the substituents on the electronic absorption spectra and fluorescence emission have been demonstrated. The fluorescence decay curves exhibit one or two decay times. The emission lifetime measurements revealed values of 3–5 ns under the excitation with 370 nm. The quantum yield was also determined. The quenching process of emission using picric acid as quencher was characterized by Stern-Volmer plots. The phenanthroline derivatives 2 and 5 possess high efficiency for the detection of picric acid.
