A cationic Ru(II) complex Ru1 with 5-phenyl-2,2′-bipyridine as ligand was synthesized and fully characterized. Ru1 exhibits significant aggregation-induced phosphorescent emission (AIPE) activity in THF/H2O. The AIPE property of Ru1 has been successfully used to detect picric acid (PA) in aqueous media. Ru1 exhibits a sensitive luminescence quenching response to PA, with a high quenching constant (KSV = 2.5 × 104 M−1) and a low limit of detection (LOD = 91 nM). In addition, Ru1 demonstrates high sensitivity and selectivity for detecting PA in different common water samples. The UV-vis absorption spectra and luminescence lifetime of Ru1 show an obvious change after the addition of PA into the Ru1 samples, indicating that the quenching process is a combination of dynamic and static quenching. The density functional theory calculations indicate that the mechanism for the detection of PA is photo-induced electron transfer.
