2-NO2-5,10,15,20-tetraphenylporphyrin (H2TPP−NO2) is shown to exist in solution as an equilibrium mixture of two NH tautomers with different spectral and photophysical properties. At 77 K in a rigid glass solution the fluorescence spectra of the ta

In the present work we study the spectral and photophysical properties of a relatively simple porphyrin system with an electron-withdrawing substituent, namely 2-nitro-5, 10, 15, 20-tetraphenylporphyrin (H2TPP-NO2). Similar β-nitro-substituted tetra

The authors suggest a new improved automated method for separate measurements of urinary porphyrins (coproporphyrins and uroporphyrins) in native urine with computer processing of spectral data. The method of dividing the total spectrum of porphyrin
