Fluorescence probes are essential tools for rapid and sensitive detection in environmental analysis and bioassays. Phenothiazine-based dyes, with their electron-rich characteristics, have been widely used in constructing electron donor-acceptor dyes for fluorescence and colorimetric analysis. This review summarizes recent advances in the performance of phenothiazine-based fluorescent probes in detecting various analytes, and discusses design rules, response mechanisms, practical applications, challenges, and future research perspectives.
Fluorescence probes, as analytical tools with the ability to perform rapid and sensitive detection of target ana-lytes, have made outstanding contributions to environmental analysis and bioassays. Considering the expanding developments in these areas, fluorophores play a key role in the de-sign of fluorescence probes. Compared to classical fluorophores, phenothiazines with elec-tron-rich characteristics have been widely applied to construct electron donor-acceptor dyes, which exhibit outstanding performance in both fluorimetric and colorimetric analysis. In addition, these probes also exhibit the pronounced ability in both solution and solid-state, achieving portable detection for environmental analysis. In this review, we summarize recent advances in the performance of phenothiazine-based fluorescent probes for detecting various analytes, especially in cations, anions, ROS/RSS, enzyme and other small molecules. The general design rules, response mechanisms and practical applications of the probes are analyzed, followed by a discussion of exiting challenges and future research perspectives. It is hoped that this review will provide a few strategies for the development of phenothiazine-based fluorescent probes.
