14-Dibenzoylene-Quaterrylene

Electrochemistry, Spectroscopy and Electrogenerated Chemiluminescence of Perylene, Terrylene, and Quaterrylene Diimides in Aprotic Solution

The electrochemistry, UV-vis spectrophotometry, photoluminescence, and electrogenerated chemiluminescence (ECL) of perylenedicarboxylic imide, perylenetetracarboxylic diimide (PDI), terrylenetetracarboxylic diimide (TDI), and quaterrylenecarboxylic diimide (QDI) were investigated. All compounds undergo two reversible one-electron reductions and one reversible one-electron oxidation reaction. Th...

Double Ionization of Quaterrylene (C40H20) in Water-Ice at 20 K with Lyr (121.6 nm) Radiation

Polycyclic aromatic hydrocarbon (PAH) molecules undergo facile ionization in cryogenic water-ices resulting in near quantitative conversions of neutral molecules to the corresponding singly charged radical cations. Here we report, for the first time, the production and stabilization of a doubly ionized, closed shell PAH in water-ice. The large PAH quaterrylene (QTR, C40H20) is readily photoioni...

This case study provides an in-depth analysis of Siemens' lessons learned when implementing knowledge management. For the analysis of the case-study data, we use established tools from the marketing literature, and integrate these with the change management literature. The aim is to provide a rich-yet-parsimonious conceptualisation of Siemens' lessons learned in dealing with two distinct implem...

Pasco et al (pp. 322–326) investigated the role of tobacco smoking as a risk factor for major depressive disorder, using data from an Australian population-based sample of women. They found both cross-sectional and longitudinal evidence for an association between smoking and depression, particularly among heavy smokers. Using a range of brain imaging techniques, de Win et al (pp. 289–296) found...
