Singlet oxygen generation by porphyrins and metalloporphyrins revisited: A quantitative structure-property relationship (QSPR) study

Singlet Oxygen Trapping Porphyrins

A Quantitative Structure-Property Relationship (QSPR) Study of Aliphatic Alcohols by the Method of Dividing the Molecular Structure into Substructure

A quantitative structure-property relationship (QSPR) analysis of aliphatic alcohols is presented. Four physicochemical properties were studied: boiling point (BP), n-octanol-water partition coefficient (lg P(OW)), water solubility (lg W) and the chromatographic retention indices (RI) on different polar stationary phases. In order to investigate the quantitative structure-property relationship ...

Singlet oxygen generation of porphyrins, chlorins, and phthalocyanines.

The production of singlet oxygen was measured indirectly for three classes of photosensitizers: porphyrins (Photofrin II, TPPS4), chlorins (MACE, DACE), and a phthalocyanine (CASPc). Buffered solutions of sensitizers and singlet oxygen acceptors were irradiated with a CW dye laser and the oxygen depletion was monitored electrochemically with a Clark-type microelectrode. A comparison of oxygen-d...

Porphyrins and Metalloporphyrins

This is another of an increasing number of human gross anatomy books being published in abbreviated form. Throughout the book each left-hand page contains quite accurate written descriptions of structures that are illustrated as line drawings on the opposite right-hand page. Even though the text is written in a telegraphic style and the drawings are small, the book still contains 443 pages. It ...

Quantitative structure-property relationship (QSPR) model for predicting acidities of ketones

Ketones are one of the most common functional groups, and ketone-containing compounds are essential in both the nature and the chemical sciences. As such, the acidities (pKa) of ketones provide valuable information for scientists to screen for biological activities, to determine physical properties or to study reaction mechanisms. Direct measurements of pKa of ketones are not readily available ...
