Research Abstract

New fluorescent ionophores containing a series of anthracene aromatic amides and naphtylmethyl-N-phenyl amides moiety based on oligo-ethylene oxide have been synthesized and its photochemical behaviors have been studied. In the absence of metal ion, these amides moiety showed a weak fluorescence emission (fluorescence "off state"). However, complexation with Ca^<2+> induced a large enhancement effect on the fluorescence intensity of 1_4 and 1_5 from the naphthalene ring (fluorescence "on" state). This behavior can be explained by in terms of the similar twisted intramolecular charge transfer relaxation mechanism. Such an "off-on" fluorescence response provided the digital detection of alkaline earth metal ions.
