Triphenyl amine based chemosensors, (2-(((2-(9H-carbazol-9-yl)phenyl)imino)methyl)-5-(diphenylamino)phenol (ortho-CPDP) and 2-(((4-(9H–carbazol-9-yl)phenyl)imino)methyl)-5-(diphenylamino)phenol (para-CPDP), showed solvent and isomerism dependent selective coloro/fluorometric sensing of multiple metal ions (Fe3 +, Al3 + and Zn2 +) with distinguishable responses. In CH3CN, ortho and para-CPDP selectively
基于三苯胺的化学传感器,(2-(((2-(9H-咔唑-9-基)苯基)亚氨基)甲基)-5-(二苯基氨基)苯酚(邻位-CPDP)和2-(((4-(9H -咔唑-9-基)苯基)亚氨基)甲基)-5-(二苯基氨基)苯酚(对-CPDP),显示出溶剂和异构体对多种金属离子(Fe 3 +,Al 3 +和Zn的选择性比色/荧光检测)2 +)与可区别的反应在CH。3 CN,邻和对位- CPDP选择地制备在添加Al的黄色3 +和Fe 3 +。这是慢慢消失了黄色的颜色邻和对位-CPDP的DMF溶液通过添加Al选择性地脱色3 +和Fe 3 +。两个邻位和对位-CPDP在CH 3 CN显示脱色的几乎相似率的Fe 3 +和Al 3 +。然而,脱色率邻和对位-CPDP在DMF中的混合物为不同的Fe 3 +(10μM,8分钟)和Al 3 +(5×10 - 4 男,40分钟)离子。Fe3 +和Al 3 +的对-CPDP的检出限为10μM500微米
