A BOPHY-based organotellurium-containing probe was synthesized and characterized via single crystal XRD for the selective and sensitive detection of Hg2+ over other metal ions. The probe detects Hg2+ in less than 1 s with a 2.5-fold enhancement in fluorescent intensity. Due to the chalcogenophilicity of mercury, Hg2+ was facilely trapped in the NTe2 chelating cavity of the probe. The probe can detect Hg2+ in the nanomolar range (62 nM) and it showed reversibility with S2− ions. The sensitivity of the probe for the detection of Hg2+ was confirmed in living HeLa cells.

基于 BOPHY 的 Hg2+ 荧光探针通过 NTe2 螯合

合成了一种基于 BOPHY 的有机碲探针,并通过单晶 XRD 对其进行了表征,用于选择性和灵敏地检测 Hg 2+而不是其他金属离子。该探针在不到 1 秒的时间内检测到 Hg 2+ ,荧光强度提高了 2.5 倍。由于汞的亲硫族元素,Hg 2+很容易被捕获在探针的NTe 2螯合腔中。该探针可以检测纳摩尔范围内的Hg 2+ (62 nM),并显示出对S 2-离子的可逆性。该探针检测Hg 2+的灵敏度在活HeLa细胞中得到证实。
