β-Lactosylated 5,15-meso-diphenylporphyrinatoiron(III) chloride was prepared by ironization of the corresponding free base porphyrin having acetylated lactoside-units followed by deacetylation with ammonia in a water-methanol mixture. The resultant 5,15-meso-bis(β-lactosylphenyl) porphyrinatoiron(III) chloride showed unique colorimetric response to calcium cation. This colorimetric response is calcium-specific and no other cations, such as sodium, potassium, or magnesium ions induced such colorimetric response. Lines of evidence including UV-vis spectra under different conditions and TEM images strongly indicate that interdigitations of the corresponding μ-oxo-dimers are responsible for this colorimetric change.
