Bambusuril-based receptors have been used in conjunction with (1)H NMR spectroscopy to recognize mixtures of inorganic anions in aqueous solutions. This was achieved by examining complexation-induced changes in the receptors' (1)H NMR fingerprints. This approach enables the simultaneous identification of up to 9 anions and the quantification of up to 5 anions using a single receptor in DMSO-d6 containing 5% D2O. Toxic perchlorate was recognized and quantified at 0.1 μM (1.8 ppb, mol mol(-1)) concentration in pure water.
基于竹节环脲的受体已与核磁共振氢谱((1)H NMR)联用，用于识别水溶液中的无机阴离子混合物。这是通过检测受体的核磁共振氢谱指纹图谱中络合诱导的变化来实现的。这种方法能够在含有5% D2O的氘代二甲亚砜(DMSO-d6)中，使用单一受体同时识别多达9种阴离子，并对多达5种阴离子进行定量分析。在纯水中，毒性高氯酸盐在0.1 μM(1.8 ppb，摩尔摩尔(-1))浓度下能够被识别和定量。
