Diketopyrrolopyrrole-based fluorescent probes for detection and bioimaging: Current progresses and perspectives

The development of fluorescent probes for detection and bioimaging is always the focuses and forefront projects in academic research and clinical diagnosis. Diketopyrrolopyrrole (DPP) dyes are widely used as fluorescent probes due to their easy functionalization, tunable photophysical properties, high fluorescence quantum yields, excellent thereto-stability and photostability. This review will highlight and focus on design principles, recognition mechanisms and applications for the detection of anions, cations, biomolecule, gases, and explosive, etc. by use of DPP-based fluorescent probes in recent three years. We hope this review provide guidelines and perspectives for readers to better understanding of novel DPP-based probes to extend the range of practical applications.
