A unique water-soluble porphyrin [5,10,15,20-tetra(3-ethoxy-4-hydroxy-5-sulfonate)phenyl porphyrin, H₂TEHPPS] was designed and synthesized, which could be used as a potential sensor for the determination of Cu²⁺. Studies were performed in the solution. The concentration of H₂TEHPPS was 5 μmol L⁻¹. The optical properties of H₂TEHPPS were investigated based on the absorption spectra. The results show that the absorbance of H₂TEHPPS at 417 nm is directly proportional to the concentration of Cu²⁺ in the range of 0 – 2.5 μmol L⁻¹. H₂TEHPPS can thus be used as a novel class of Cu²⁺ sensors.
