Therefore, it is highly desirable to develop a selective and sensitive assay for the detection of PPi to measure the concentration of phosphate-containing metabolites in biological samples. Although several methods such as chromatography [7], bioluminescence assay, [8] electrochemical [9] and fluorescent biosensors [10] have been proposed for the detection of PPi and ATP, these methods exhibit some disadvantages. Chromatography is restricted by the difficult separation of the complex from the sample matrix. Low specificity and sensitivity are always a challenge in electrochemical sensors. Recently, many reports have proposed suitable molecules as sensing probes for ATP [11–13] and PPi [14–16]. However, these methods typically suffer from several limitations, such as low signal intensities, high photobleaching and low solubility of the sensing probe in aqueous solutions. Thus, the development of a new selective fluorescence probe for the detection of both PPi and ATP is of tremendous interest and importance to analytical chemists.
