Dodecylbenzenesulfonic anion (DBSA) is often found in waste oil, which indicates the possibility of distinguishing waste oil by determination of DBSA. For this purpose, a new supramolecular fluorescence sensor based on tris(thiourea) and 1,8-naphthanlimide derivative moieties was designed and synthesized. Fluorescence spectra of the sensor with addition of dodecylbenzenesulfonic anion showed evident fluorescence enhancement due to their PET quenching system triggered by host-guest hydrogen-bonding interaction, which demonstrated that a new method to distinguish waste oil with the tripodal sensor via fluorescence spectroscopy can be established. Through a series of experiments, this method was found to be simple, effective and practicable.

Keywords:Fluorescence probe; Thiourea; Hydrogen-bond; Dodecylbenzenesulfonic anion; Waste oil
