title: A new 2-(2'-hydroxyphenyl)quinazolin-4(3H)-one derived acylhydrazone for fluorescence recognition of Al3.
abstract: A new 2-(2'-hydroxyphenyl)quinazolin-4(3H)-one derived acylhydrazone (QP) was designed and synthesized as a fluorescent sensor. In Tris∙HCl buffer (10mM, pH7.4)/ethanol (1/9, v/v) solution, QP exhibits a highly selective fluorescence response to Al3+over other metal ions with a significant blue-shifted and enhanced emission at 473nm. QP interacts with Al3+reversibly through a 1:2 binding ratio with a detection limit of 4.79×10-8M. Potential applicability of QP for Al3+detection in tap and lake water samples were also examined by 'proof-of-concept' experiments.
