A series of diketopyrrolopyrrole-based fluorescent probes (<b>DPP-C2</b>, <b>LysoDPP-C2</b>, <b>LysoDPP-C3</b>, and <b>LysoDPP-C4</b>) have been developed for the detection of low pH and Zn<sup>2+</sup> in an AND logic fashion. The chelation of Zn<sup>2+</sup> or the protonation of a morpholine moiety within these probes results in a partial increase in the fluorescence intensity, an effect ascribed to suppression of one possible photo-induced electron transfer (PET) pathway. In contrast, a larg ...[more]
