Objective: To study the electronic spectra of tetraphenylporphyrine, and, so as to screen better photosensitive agents. Methods: The UV-VIS detect method was adopted to test the spectra of tetraphenylporphyrine and its substitutive derivatives under different conditions. Results: It was found that the tetraphenylporphyrine and its substitutive derivatives exist as monomer in organic solvents with different polarity, but differences were found among electronic spectra of compounds with different structure. Conclusion: At least, 2 kinds of better photosensitive agents could be screened out from the compounds studied.
