A novel series colorimetric and off-on fluorescent chemosensors (2a, 2b, 2c) were designed and synthesized, which showed reversible and highly selective and sensitive recognition toward Fe(3+) over other examined metal ions. Upon addition of Fe(3+), sensors (2a, 2b) exhibit remarkably and 2c exhibits moderate enhanced absorbance intensity and color change from colorless to pink in CH(3)OH-H(2)O(1:1, v/v). The three compounds (2a, 2b, 2c) may therefore be applicable as rhodamine-based turn-on type fluorescent chemosensors.
设计并合成了一系列新型的比色和荧光化学传感器(2a、2b、2c),它们对 Fe(3+)具有可逆的、高度选择性和灵敏的识别能力,而对其他测试的金属离子则没有。加入 Fe(3+)后,传感器(2a、2b)在 CH(3)OH-H(2)O(1:1,v/v)中表现出显著的、2c 则表现出适度增强的吸收强度和颜色变化,从无色变为粉红色。因此,这三种化合物(2a、2b、2c)可以作为基于罗丹明的荧光化学传感器。
