Abstract :In the present work, the novel aminopyrene substituted monospiro/dispiro cyclotriphosphazenes ( 6 and 7 ) have been synthesized. This compounds were characterized general spectroscopic techniques such as mass, 1 H and 31 P NMR spectrometry. The photophysical and chemosensor properties toward various metals (Fe 3+ , Cr 3+ , Co 2+ , Al 3+ , Hg + , Mn 2+ , Ni 2+ , Cu 2+ , Cd 2+ , Zn 2+ , Mg 2+ , Ca 2+ , Ba 2+ , Li + , Na + , K + , Cs + ) in THF solutions of aminopyrene substituted compounds were investigated by fluorescence spectroscopy. The metal sensing results showed that compounds 6 and 7 can be candidate fluorescent chemosensors for Cu 2+ and Fe 3+ ions due to their displaying high selectivity and low limit of detection.
