revealed that treating DPAC-bisC4P with dicarboxylate guests capable of forming pseudo-macrocyclic host-guest complexes via multiple hydrogen bonding interactions between the dicarboxylates and calix[4]pyrrole moieties, led to a blue-shift in the emission of the phenazine core. The binding-based fluorescence tuning features of DPAC-bisC4P allows the underlying binding events and inferred structural changes
