A theoretical framework for modelling the electronic structure of absorbing molecules that may contribute to explain and even predict phenomena where a singlet exciton is converted to triplet is reported. The pathway is ...

The efficiencies of singlet oxygen production from the singlet and triplet states of a series of anthracene derivatives in acetonitrile are reported. For anthracene and for all of the anthracene meso derivatives studied, ...

Three lipid-soluble furan derivatives, 2,5-disubstituted with different n-alkyl chains, and a terminal trimethylammonium group were obtained by reaction of a metalated monoalkylfuran with alkyl dihalides under conditions ...

The synthesis of the biologically active alkaloid simulenoline, isolated from the roots of Zanthoxylum simulans, is reported. The natural product was assembled from simple commercial reagents via initial domino ...

Photosensitized oxidations involve the generation of radicals (type I mechanism) and/or the production of singlet molecular oxygen (1O2) (type II mechanism). Phenalenone (PN) is one of the well-known type II photosensitizers ...

The quantum yields for singlet oxygen production by diluted solutions of an Argentine crude oil and its SARA (saturates, aromatics, resins and asphaltenes) fractions were obtained by direct detection of the characteristic ...
