Extended O-doped polycyclic aromatic hydrocarbons

The synthesis of O-doped benzorylenes, in which peripheral carbon atoms have been replaced by oxygen atoms, has been achieved for the first time. This includes key high-yielding ring-closure steps which, through intramolecular C−O bond formation, allow stepwise planarization of oligonaphthalenes. Single-crystal X-ray diffraction showed that the tetraoxa derivative forms remarkable face-to-face π–π stacks in the solid state, a favorable solid-state arrangement for organic electronics

Controlling coordination reactions and assembly on a Cu(111) supported boron nitride monolayer

We report the formation of a metal–organic network on a BN/Cu(111) template by codeposition of carbonitrile-functionalized porphyrin derivatives (2H-TPCN) with Co atoms in an ultrahigh vacuum environment. The resulting metallo-supramolecular structure explored by scanning tunneling microscopy and spectroscopy features a distinct 4-fold coordination motif. Furthermore, we demonstrate an in situ metalation of the tetrapyrrole macrocycles with deposited Co atoms yielding Co-TPCN directly on the BN sheet. Our results provide perspectives for the formation of coordination networks on BN and related systems featuring structural, electronic, and magnetic properties unachievable on metallic supports

Data for Two-dimensional ketone-driven metal–organic coordination on Cu(111)

Two-dimensional metal-organic nanostructures based on the binding of ketone groups and metal atoms were fabricated by depositing pyrene-4,5,9,10-tetraone (PTO) molecules on a Cu(111) surface. The strongly electronegative ketone moieties bind to either copper adatoms from the substrate or co-deposited iron atoms. In the former case, scanning tunnelling microscopy images reveal the development of an extended metal-organic supramolecular structure. Each copper adatom coordinates two ketone ligands of two neighbouring PTO molecules, forming chains that are linked together into large islands via secondary van der Waals interactions. Deposition of iron atoms leads to a transformation of this assembly resulting from the substitution of the metal centres. Density functional theory calculations reveal that the driving force for the metal substitution is primarily determined by the strength of the ketone-metal bond, which is higher for Fe compared to Cu. This second class of nanostructures displays a structural dependence on the rate of iron deposition

Jaarboek voor de intensievezorgenverpleegkundige 2010

Het Jaarboek voor de intensievezorgenverpleegkundige 2010 wordt uitgegeven ter gelegenheid van het 28ste jaarcongres van de Vlaamse Vereniging van Intensieve Zorgen Verpleegkundigen (VVIZV). Het is samengesteld met teksten die aangeleverd werden door elke spreker op het jaarcongres, en die aldus een synthese vormen van de respectievelijke voordrachten. Dit jaarboek kan door verpleegkundigen die tewerkgesteld zijn op een dienst intensieve zorg als referentie gehanteerd worden, en dienst doen als naslagwerk voor de verpleegkundige praktijk
