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.
