Selective Fluorescence Chemosensor for Al3+ based on Antipyrine with Furfural Attached Allyl System

By incorporating Furfural-Antipyrine as coordinate sites into the fragment of receptor FBH-AP has been used as an artificial chemosensor for selective recognition of transition metals. The strong fluorescence emission at 388 nm of the receptor FBH-AP is effectively and selectively quenched by Al3+. A 1:1 complex is formed between the FBH-AP and Al3+ is determined by jobs plot and their common interferent ions do not show any interference with the Al3+. It is anticipated that the antipyrine could be a good candidate probe and has potential application for Al3+ determination.
