✦ Synopsis

A novel fluorescent sensor L1 exhibiting selective H 2 PO 4 À sensing ability was synthesized. The initial conformation of L1 was controlled via intramolecular hydrogen bonding and the switching/gating function was achieved by disturbing the intramolecular hydrogen bonds before and after interaction with H 2 PO 4 À .
