A water-soluble turn-on fluorescent probe PNAP for pH has been designed and synthesized. PNAP was consist of pyrene as fluorophore and morpholine as receptor. Owing to the photoinduced electron transfer (PET) effect, the fluorescence of PNAP was quenched, while PNAP exhibited a remarkable "turn-on" fluorescence with the increase of acidity. Notably for its pK of 2.15, PNAP was one of the pH fluorescent probes used in extremely acidic environments. Furthermore, PNAP also displayed good repeatability, strong anti-ion interference ability, high sensitivity and selectivity toward pH. In addition, PNAP has been successfully applied to the test strips and monitor the pH of environment water samples and realistic samples, showing its good promising prospect.
一种用于检测pH值的水溶性荧光开启型探针PNAP已被设计并合成。PNAP由芘作为荧光团和吗啉作为受体组成。由于光诱导电子转移（PET）效应，PNAP的荧光被猝灭，而随着酸度增加，PNAP呈现出显著的“开启”荧光。值得注意的是，其pK为2.15，PNAP是用于极端酸性环境的pH荧光探针之一。此外，PNAP还表现出良好的重复性、较强的抗离子干扰能力、对pH的高灵敏度和选择性。此外，PNAP已成功应用于测试条，并用于监测环境水样和实际样品的pH值，显示出良好的应用前景。
