Journal ArticleDOI
Some new aspects related to the synthesis of meso-substituted porphyrins
TL;DR: A general analysis of the steps of the Rothemund reaction has been presented in this article, which allowed for a better understanding and a significant improvement of this reaction as a synthetic method in some of the previously known difficult syntheses.
Journal ArticleDOI
Photoacoustic Measurements of Porphyrin Triplet-State Quantum Yields and Singlet-Oxygen Efficiencies

TL;DR: In this paper, photoacoustic calorimetry was used to measure the quantum yields of singlet molecular oxygen production by the triplet states of tetraphenylporphyrin (TPP), ZnTPP and CuTPP in toluene, yielding values of 0.67 0.14, 0.68 0.19 and 0.03 0.07 quantum yield.
Journal ArticleDOI
Mechanisms of singlet-oxygen and superoxide-ion generation by porphyrins and bacteriochlorins and their implications in photodynamic therapy.

TL;DR: Recommendations are given for the design of more effective PDT protocols employing new halogenated and sulfonated bacteriochlorins and their analogous porphyrins as photosensitizers of singlet oxygen and the superoxide ion.
Journal ArticleDOI
Heavy-atom effects on metalloporphyrins and polyhalogenated porphyrins
Emı́lia G. Azenha,Arménio C. Serra,Marta Pineiro,Mariette M. Pereira,J. Sérgio Seixas de Melo,Luis G. Arnaut,Sebastião J. Formosinho,A. M. d'A. Rocha Gonsalves +7 more
TL;DR: In this article, the photophysics of halogenated and metallated tetrakisphenylporphyrins were investigated using single-photon counting, photoacoustic calorimetry and luminescence techniques.
Journal ArticleDOI
Highly active phosphite gold(I) catalysts for intramolecular hydroalkoxylation, enyne cyclization and furanyne cyclization
Maria Camila Blanco Jaimes,Frank Rominger,Mariette M. Pereira,Rui M. B. Carrilho,Sónia A. C. Carabineiro,A. Stephen K. Hashmi,A. Stephen K. Hashmi +6 more
TL;DR: New and highly active mononuclear phosphite gold(I) catalysts are described and turn-over numbers for the furan-yne reaction and the two-fold hydroalkoxylation of alkynes are reported.
