The spectra of porphyrins meso-substituted by 4-dimethylaminophenyl groups and protonated at the central pyrrole nitrogens show strong new bands in the visible (450–600 nm) and far-red (700–780 nm). On complete protonation the observed spectra ar

The quenching of triplet C60 by phenols is greatly enhanced by addition of pyridines, which also lower the phenol voltammetric oxidation potentials. Flash photolysis shows that the products of this quenching reaction are the C60•- anion radical, ne

In order to clarify mechanisms of excited state interactions in hydrogen-bonded pairs, we have studied the kinetics of dynamic quenching of singlet and triplet fluorenone by a series of alcohols, phenols, and related compounds, in which hydrogen-bond

Hydrogen-bonding and protonation are fundamental factors controlling potentials and mechanisms in the reduction of quinones. These are studied systematically in benzonitrile, acetonitrile, and dimethylsulfoxide solutions by cyclic voltammetry of a se

Hydrogen bonding equilibria, redox potentials and quenching of tripletC60 in naphthol solutions containing added pyridines are studied by absorption spectroscopy, nanosecond flash photolysis and cyclic-voltammetry. It is shown that the quenching reac

Photoprocesses in benzonitrile solutions of C60 and chloranil (CA) have been studied by complementary techniques of nanosecond laser photolysis and Fourier transform EPR. Direct oxidation of 3C60 by CA is slow (k = (2.0 ± 0.3) × 107 M-1 s-1), consi

Spin-polarized transient EPR spectra measured at 9 GHz (X-band) and 24 GHz (K-band) are observed for the metalloporphyrin heterodimers formed by MTTAP (metal/free base meso-tetrakis[4-trimethylanilinium]porphyrin, M = Zn, Mg or H2) and CuTSPP (copper

Proton NMR spectroscopy has been used to study the protonation of meso-tetraphenylporphyrins with zero, one, or four para dimethylamino substituents. Changes in the spectra are similar for corresponding protons through this series of compounds. We gi

Successive protonation by trifluoroacetic acid of meso-tetraphenylporphyrin derivatives bearing one, two, or four p-dimethylamino groups gives rise to new types of spectra. With one free amino group, the spectrum of the centrally protonated porphyrin

The study of rates and radical yields in charge-transfer (CT) interactions between organic triplets and simple anions has been extended to triplets of 1-sulfonate, 1,5-disulfonate, and 2,6-disulfonate derivatives of 9,10-anthraquinone and of fluoresc
