Bisbenzimidazoles with Benzenediyl Spacer: An Efficient Fluorophore for Dihydrogenphosphate Sensing and Targeted Living Cell Imaging

Key Points

• The aim is to develop an efficient fluorescent probe for selectively detecting dihydrogen phosphate ions.
• Created a bisbenzimidazole-based fluorescent probe
• Utilized a CH₃CN-water mixed solvent system for testing
• Assessed fluorescent properties in the presence of dihydrogen phosphate
• The probe showed strong fluorescence response to dihydrogen phosphate ions
• Demonstrated selective sensing capability
• Enabled targeted imaging in living cells
