Abstract
Abstract A novel and simple fluorescent probe, 7-methoxychromone-3-carbaldehyde-(3′4′5′-trimethoxybenzoyl) hydrazone (L), was designed and synthesized. The probe L presented outstanding “turn-on” fluorescence response towards Al3+ over most other competitive ions in ethanol. The detection limit of L for recognizing Al3+ was measured to be 2.14 × 10−7 M. According to these excellent properties, the detecting of Al3+ on filter papers was studied successfully. Photoinduced electron transfer (PET) process, coupled with the C N isomerisation process, is put forward to interpret the obvious fluorescence response.
