It is always a significant challenge to develop a probe for Th4+ in the environment and in vivo under extreme acidity conditions, especially on real-time in the field. Herein, a new Th4+ fluorescent probe N1′,N2′-bis((3-hydroxytetrastyrene-2yl)methylene malonohydrazide (BH-TPE) was designed and studied. It could realize to detect Th4+ in a ratiometric way, which showed relative strong blue fluorescence at 450 nm and yellow-green fluorescence at 522 nm in the absence or present of Th4+, respectively, with good selectivity and sensitivity under...
