Bis(3-(1,1-diphenylethoxy) propanoate) silicon phthalocyanine was obtained from the reaction of 3-(1,1-diphenylethoxy) propionic acid with SiPcCl2. The newly prepared compounds were characterized by H-1 NMR, FT-IR, mass spectrometry and UV-vis spectroscopy. The singlet oxygen quantum yield for silicon phthalocyanine, which has the potential to be a photosensitizer, was determined as 0.13 by chemical method. Finally, metal ion selectivity of bis(3-(1,1-diphenylethoxy) propanoate) silicon phthalocyanine was determined by UV absorption spectroscopy. A total of 11 metal ions (Mg2+, Mn2+, Na+, Ni2+, Zn2+, Fe3+, Ba2+, Cd2+, Cu2+, Co2+, and Ag+) were used for testing. Of these metal ions, only the Fe3+ ion was selectively determined.
