Computational choreography: dissecting the dance of hydrogen bonding and π-π stacking in the fluorescence discrimination mechanism of ciprofloxacin with supramolecular assembly.

The detailed binding insight between the fluorophore and analyte plays a pivotal role in the design of an efficient chemosensor for water pollution. In this study, we designed a picolinic acid-functionalized calix[4]pyrrole ligand (PCACP). When testing out the fluorescence study with selected antibiotics, we observed remarkable enhancement of fluorescence spectra in the presence of ciprofloxacin, singling out the PCACP_Ciprofloxacin complex.
