Novel ESIPT fluorescent benzazolyl-4-quinolones: Synthesis, spectroscopic characterization and photophysical properties

“…Since the discovery of penicillin, the development of novel synthetic or natural molecules with highly specific antibacterial properties has attracted great interest [6,7] in which context, oxo-quinolines have been the focus of attention [8][9][10]. To overcome the problem of the development of bacterial resistance to antibacterial compounds, novel quinolones with specific properties have been developed [11][12][13][14][15][16][17][18].…”
