Naked-Eye Detection of Phosphate Ions in Water at Physiological pH: A Remarkably Selective and Easy-To-Assemble Colorimetric Phosphate-Sensing Probe

Naked-Eye Detection of Phosphate Ions in Water at Physiological pH: A Remarkably Selective and Easy-To-Assemble Colorimetric Phosphate-Sensing Probe

A color change occurs when phosphate anions are added to an aqueous solution of H‐bpmp (2,6‐bis(bis(2‐pyridylmethyl)aminomethyl)‐4‐methylphenol), zinc perchlorate, and pyrocatechol violet in a 1:2:1 molar ratio. The photograph shows the color of the mixture in the presence of no anions (far left), p...

Zusammenfassung:A color change occurs when phosphate anions are added to an aqueous solution of H‐bpmp (2,6‐bis(bis(2‐pyridylmethyl)aminomethyl)‐4‐methylphenol), zinc perchlorate, and pyrocatechol violet in a 1:2:1 molar ratio. The photograph shows the color of the mixture in the presence of no anions (far left), phosphate ions (yellow solution), and various other inorganic anions.
