Synthesis of 5,10,15-Tris(4-nitrophenyl)-20-hydroxylphenylporphyrin and its Spectrum Study
Abstract:
5,10,15-Tris(4-nitrophenyl)-20-hydroxylphenylporph-yrin was synthesized by a novel method which was for the nitration of the phenyl groups of 5-(4-hydroxylphenyl)-10,15,20- triphenylporphyin(MHTPP) using NaNO2 and trifluoroacetic acid(TFA) and characterized using mass spectrometry, NMR spectroscopy, UV-visible, IR spectrometry. The mild reaction conditions produced higher yields and minimum macrocyclic degradation. Its fluorescence spectra was studied compared with MHTPP and tetraphenylporphyrin(TPP). The results showed that the absorption and emission bands of the product experienced red shifts and the fluorescence intensity weakened compared with MHTPP and TPP.
