Synthesis of Porphyrins Substituted by Triarylamine and Theirs Spectrum Properties

Porphyrins substituted by triarylamine at the meso-positions were synthesized by direct condensation of pyrrole and 4-diphenylamino-benzaldehyde, 4-（ bis （p-tolyl） amino）-benzaldehyde and 4- bis （4-methoxyphenyl） amino] benzaldehyde, respectively, and their structures were charactered by mass spectrum （MS）, nuclear magnetic resonance spectroscopy （^1H-NMR） and ultraviolet absorption spectrometry （UV-visible）. Excited with UV light, the energy was transferred to the porphyrin core and reemitted red light. In comparison with tetraphenylporphyrin （TPP）, the Soret bands were redshifted by 26-31 nm, and the photoluminescence spectra shifted by 23-31 nm toward higher wavelengths. The quantum yields of tetra-4-diphenylamin- ophenylporphyrin, tetra-4- bis （p-tolyl） amino ]-phenylporphyrin and tetra-4- bis （4-methoxyphenyl） amino] phenylporphyrin were 0.20, 0.21 and 0.23, respectively.
