A new pH fluorescent probe 2,8-bis(acridin-9-ylethynyl)-6,12-5,11-methanodibenzo[,][1,5]diazocine (TBN), which has two acridine moieties attached to Tröger's base, is a useful fluorescent probe for monitoring extreme acidic and alkaline pH. TBN displays an excellent pH dependent behavior and responds linearly to extreme conditions in the pH ranges of 1.4-3.4 and 12.5-15.0. TBN can represent a novel type of fluorescent probe with perfect emission properties in extreme acidic and alkaline conditions by utilizing only one functional group.
一种新型pH荧光探针2,8-双(吖啶-9-基乙炔基)-6,12-5,11-亚甲基二苯并[,][1,5]二氮杂环辛四烯(TBN),其有两个吖啶部分连接到特罗格碱上,是一种用于监测极端酸性和碱性pH的有用荧光探针。TBN表现出优异的pH依赖性行为,并且在1.4 - 3.4和12.5 - 15.0的pH范围内对极端条件呈线性响应。通过仅利用一个官能团,TBN可以代表一种在极端酸性和碱性条件下具有完美发射特性的新型荧光探针。
