[structure: see text] Novel colorimetric receptors for selective fluoride ion sensing containing anthraquinone as chromogenic signaling subunit and urea (N,N' '-(9,10-dihydro-9,10-dioxo-1,2-anthracenediyl)bis[N'-phenyl])/thiourea (N,N' '-(9,10-dihydro-9,10-dihydro-9,10-dioxo-1,2-antrhacenediyl)bis[N-phenyl]) binding sites have been reported. These receptors have shown no affinity for other halide ions (Cl-, Br-, and I- ions). Well-defined color change in the visible region of the spectrum was observed upon addition of fluoride ion in DMSO/CH3CN solution of the receptors 1 and 2.
[结构:见正文] 已报道了用于选择性氟离子传感的新型比色受体,其含有蒽醌作为发色信号亚基以及脲(N,N''-(9,10-二氢-9,10-二氧代-1,2-蒽二基)双[N'-苯基])/硫脲(N,N''-(9,10-二氢-9,10-二氢-9,10-二氧代-1,2-蒽二基)双[N-苯基])结合位点。这些受体对其他卤离子(Cl-、Br-和I-离子)没有亲和力。在受体1和2的二甲基亚砜/乙腈溶液中加入氟离子后,在光谱的可见区域观察到明确的颜色变化。
