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, ¹H
and ³¹P NMR spectrometry. The photophysical and chemosensor
properties toward various metals (Fe³⁺, Cr³⁺, Co²⁺,
Al³⁺, Hg⁺, Mn²⁺, Ni²⁺, Cu²⁺,
Cd²⁺, Zn²⁺, Mg²⁺, Ca²⁺, Ba²⁺,
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 Cu²⁺ and
Fe³⁺ ions due to their displaying high selectivity and low limit of
detection.
