Pyridine based fluorescence probe, DFPPIC and its functionalized Merrifield polymer has been synthesized, characterized and used as an arsenate selective fluorescence sensor. Arsenate induced fluorescence enhancement is attributed to inter-molecular H-bonding assisted CHEF process. The detection limit for arsenate is 0.001 μM, much below the WHO recommended tolerance level in drinking water. DFPPIC can detect intracellular arsenate in drinking water of Purbasthali, West Bengal, India efficiently. Graphical Abstract DFPPIC and its Merrifield conjugate polymer are used for selective determination and removal of arsenate from real drinking water samples of Purbasthali, a highly arsenic contaminated region of West Bengal, India. DFPPIC is very promising to imaging arsenate in living cells.
基于吡啶的荧光探针DFPPIC及其功能化的 Merrifield 聚合物已被合成、表征，并用作砷酸盐选择性荧光传感器。砷酸盐诱导的荧光增强归因于分子间氢键辅助的 CHEF 过程。砷酸盐的检测限为 0.001 μM，远低于世界卫生组织推荐的饮用水耐受水平。DFPPIC 能够有效检测印度西孟加拉邦普尔巴斯塔利饮用水中的细胞内砷酸盐。图形摘要DFPPIC及其 Merrifield 共轭聚合物用于从印度西孟加拉邦一个砷污染严重的地区——普尔巴斯塔利的实际饮用水样本中选择性测定和去除砷酸盐。DFPPIC 在活细胞中对砷酸盐进行成像非常有前景。
