AgBr与TabHPF_6（TabH = 4-（三甲基铵基）苯乙撑）的反应容易产生独特的一维配位聚合物[（TabH）（AgBr_2）]_n（1），由阴离子链[AgBr_2]_n ~-与TabH ~+阳离子形成氢键组成。通过测试其电阻和稳定性，在暴露于氨和七种常见的有机胺在水中的环境条件下，化合物1被发现表现出良好的稳定性和重现性高的灵敏度对这些分析物在低浓度。特别是，它可以选择性地检测水中的NH3，检测限低至0.05 ppm。这种化学电阻传感系统具有高效监测氨和胺的潜力，这些氨和胺是造成水污染、富营养化、食品污染和工业危害的原因。
Reaction of AgBr with TabHPF6(TabH = 4-(trimethylammonio)benzenethiol) readily produces a unique one-dimensional coordination polymer [(TabH)(AgBr2)]n(1), consisting of anionic chains [AgBr2]nn–with hydrogen bonds to TabH+cations. By examining its electrical resistance and stability upon exposure to ammonia and seven common organic amines in water under ambient conditions, compound1is found to exhibit good stability and reproducibly high sensitivity toward these analytes at low concentrations. Especially, it can selectively detect NH3in water with the detection limit as low as 0.05 ppm. This chemiresistive sensing system has the potential for highly efficient monitoring of ammonia and amines responsible for water pollution, eutrophication, food contamination, and industrial hazards.
