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

Implication

Fluorescent probe demonstrates selective detection of dihydrogen phosphate in living cells, suggesting new imaging applications.

Abstract

A bisbenzimidazole-based fluorescent probe (PBZ) has been developed for the selective detection of dihydrogen phosphate (H₂PO₄⁻) ions in a CH₃CN–water (7:3, v/v) mixed solvent system. The probe exhibited pronounced spectral...
