Four kinds of porphyrin compounds have been synthesized by simple method, which involve tetraphenylporphyrin (TPP), meso-tetrashydroxyl phenyl porphyrin (TPPS_4), meso-tetrahydroxylphenyl porphyrin , and meso-tetramethoxyphenyl porphyrin . Analysis of visible spectrum shows that the substitutance on benzene ring and polarity of solvent make their spectrum move toward blue or red, which is of importance to improve porphyrin compounds' photoabsorption performance.
