Journal ArticleDOI
Physical mechanisms of generation and deactivation of singlet oxygen.
TL;DR: Reactions of O2(∆g) are associated with significant applications in several fields, including organic synthesis, bleaching processes, and, most importantly, the photodynamic therapy of cancer, which has now obtained regulatory approval in most countries for the treatment of several types of tumors.

Alkynylpyrenes as Improved Pyrene-Based Biomolecular Probes with the Advantages of High Fluorescence Quantum Yields and Long Absorption/Emission Wavelengths
TL;DR: The photochemical properties of various alkynylpyrene derivatives have been investigated in detail with a view to developing a new class of pyrene-based biomolecular probes and the detectabilities of the labeled biomolecules were significantly improved.

TL;DR: The catalyst system formed leads to monofluorinated compounds selectively (see example) without the necessity for an excess of the alkane substrate.
Journal ArticleDOI
Silver-Catalyzed Oxidative Activation of Benzylic C ? H Bonds for the Synthesis of Difluoromethylated Arenes
TL;DR: A mild and catalytic method to form difluoromethylated arenes through the activation of benzylic C-H bonds has been developed and is operationally simple and amenable to gram-scale synthesis.
Journal ArticleDOI
Photosensitized Generation of Singlet Oxygen
TL;DR: The most important deactivation paths of fluorescence quenching by O2 are again directed by excess energies and charge-transfer interactions similar to triplet-state quench by O3, which leads to lower efficiencies to singlet oxygen generation.
