was observed in the EtOH/HO (4/1, v/v) solution of (Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Fe, Hg, Mg, Mn, Pb, Sr, Zn). The limits of detection of probe for Fe ions was calculated to be as low as 0.70 M, and it had excellent anti-interference ability. The probe complexed with Fe ions at 1:1, and the complexation constant was 3.93 × 10 M. The probe realized the detection of Fe oxidation to Fe, and the
本研究以β-二酮、取代芳香醛和乙酸铵为原料,采用NCS催化剂,通过环缩合反应高效合成2,4,5-三取代咪唑,并通过HR-MS、FT-IR、H和C NMR进行了表征。光谱学。发现了一种新型荧光传感器4-(1-菲[9,10-]咪唑-2-基)-二苯基苯胺()用于检测Fe离子。探针在溶液中表现出强烈的蓝色辐射。在存在 Fe 离子的情况下,在 (Ag、Al、Ba、Ca、Cd、Co、Cr、铜、铁、铁、汞、镁、锰、铅、锶、锌)。经计算,该探针对Fe离子的检出限低至0.70 M,具有良好的抗干扰能力。该探针与Fe离子以1:1络合,络合常数为3.93×10 M。该探针实现了Fe氧化成Fe的检测,且pH在4.0~7.0的环境中表现出良好的稳定性,保证了其潜力。应用前景。添加 EDTA 后也表现出良好的可逆性。此外,Fe 的活力在活细胞成像中具有实际应用。
