Journal ArticleDOI
Organic Photoredox Catalysis
TL;DR: An overview of the basic photophysics and electron transfer theory is presented in order to provide a comprehensive guide for employing this class of catalysts in photoredox manifolds.
Journal ArticleDOI
Fluorescent dyes and their supramolecular host/guest complexes with macrocycles in aqueous solution.
TL;DR: Fluorescent Dyes and Their Supramolecular Host/Guest Complexes with Macrocycles in Aqueous Solution and how these complexes interact with each other and with solvent-free substrates is studied.
Journal ArticleDOI
Transition-Metal-Free Coupling Reactions
TL;DR: This research presents a new generation of state-of-the-art materials for bioorganic and non-volatile organometallic research that combines high-performance liquid chromatography and high-tech materials for organic synthesis.
Journal ArticleDOI
Metal‐Free, Cooperative Asymmetric Organophotoredox Catalysis with Visible Light
TL;DR: The dawn of old stars: Classic xanthene dyes like eosin Y (gr. eoς=goddess of dawn) and green-light irradiation can replace precious metal complexes for the organocatalytic asymmetric -alkylation of aldehydes rendering the process purely organic.

Metal-free, cooperative asymmetric organophotoredox catalysis with visible light
TL;DR: The dawn of old stars: Classic xanthene dyes like eosin Y (gr. eoς=goddess of dawn) and green-light irradiation can replace precious metal complexes for the organocatalytic asymmetric -alkylation of aldehydes rendering the process purely organic as discussed by the authors.

Journal ArticleDOI
Photodynamic sensitization by 8-methoxypsoralen via the singlet oxygen mechanism.
W. Poppe,L. I. Grossweiner +1 more
TL;DR: Evidence is presented to indicate that the binding of 8-MOP to double stranded poly(dA-dT) inhibits its ability to sensitize via this mechanism, and that singlet oxygen (lo2) generated by triplet energy transfer is the principal reactive intermediate in the inactivation of lysozyme and oxidation of aqueous iodide ion.
Journal ArticleDOI
On the mechanism of quenching of singlet oxygen by amines-iii. evidence for a charge-transfer-like complex
TL;DR: In this paper, a series of amines were found to quench singlet oxygen in the order tertiary > secondary > primary, with a reasonable correlation between the log of their rate constant of quenching and their ionization potential.
Journal ArticleDOI
The cytotoxic and photodynamic inactivation of micro-organisms by Rose Bengal.
TL;DR: Yeasts from chilled foods were killed in illuminated solutions of Rose Bengal but a light intensity of 315 microE/m2/s was needed for a death rate comparable with that of bacteria, and Singlet oxygen was identified as the lethal agent.
Journal ArticleDOI
Distances between the functional sites of the (Ca2+ + Mg2+)-ATPase of sarcoplasmic reticulum.
TL;DR: Considerations of the molecular dimensions of the ATPase polypeptide indicate that while the two Ca2+ sites are close to each other, the Ca2- sites and the nucleotide site are quite remote in the three-dimensional structure of the enzyme.

Photodynamic Reactions in Photomedicine
TL;DR: Some of these derivatives are produced by metabolic reactions, and, of special pertinence to this chapter, several are produced in good yield by sensitized photobiologic processes involving visible and near-UV radiation.
