Be a powerful technique for convenient detection of pH change in living cells, especially at subcellular level, fluorescent probes has attracted more and more attention. In this work, we designed and synthesized three rhodamine lactam modulated fluorescent probes RS1, RS2 and RS3, which all respond sensitively toward weak acidity (pH range 4–6) via the photophysical property in buffer solution without...
A novel, solvent-dependent “off–on” probe with benzoylthiourea moiety as the functional receptor and fluorescein as the fluorophore was designed for monitoring of Ag + in EtOH–H 2 O (2:8, v/v) solution and Zn 2+ in CH 3 CN–H 2 O (2:8, v/v) solution at physiological range with sufficient selectivity and sensitivity. The Ag + promoted desulfurization of...
