Intramolecular deactivation processes in complexes of salicylic acid or glycolic acid with Eu(III).
The complexation of Eu(III) by 2-hydroxy benzoic acid (2HB) or glycolic acid (GL) was investigated using steady-state and time-resolved laser spectroscopy. Experiments were carried out in H(2)O asExpand

Separation of several oxoanions with a special chelating resin containing methylamino-glucitol groups
Abstract Certain oxoanions form complexes with polyols if the hydroxy groups have a sterically favoured position. Similar properties were found for the chelating resin Wofatit MK 51 which containsExpand

Missing Building Blocks Defects in a Porous Hydrogen–bonded Amide‐Imidazolate Network Proven by Positron Annihilation Lifetime Spectroscopy
In situ imidazolate-4,5-diamide-2-olate (L2) linker generation under conventional electrical (CE) heating and microwave (MW)-assisted conditions leads to the formation of the porous three-dimensionalExpand

Separation of the oxoanions of germanium, tin, arsenic, antimony, tellurium, molybdenum and tungsten with a special chelating resin containing methylaminoglucitol groups
Abstract The chelating resin Wofatit MK 51, which contains methylaminoglucitol groups, forms complexes with different oxo anions. Moreover it can react as a weakly basic anion-exchange resin. LoadingExpand

Synthesis of mono- and disubstituted porphyrins: A- and 5,10-A2-type systems.
General syntheses have been developed for meso-substituted porphyrins with one or two substituents in the 5,10-positions and no beta substituents. 5-Substituted porphyrins with only one mesoExpand

9,10-diarylanthracenes as molecular switches: syntheses, properties, isomerisations and their reactions with singlet oxygen.
A series of 9,10-diarylanthracenes with various substituents at the ortho positions have been synthesised by palladium-catalysed cross-coupling reactions. Such compounds exhibit interesting physicalExpand

Pd-catalyzed [2+2+1] coupling of alkynes and arenes: phenol diazonium salts as mechanistic trapdoors.
Alkynes and phenol diazonium salts undergo a Pd-catalyzed [2+2+1] cyclization reaction to spiro[4,5]decatetraene-7-ones. This structure was confirmed for one example by X-ray single-crystal structureExpand

A supramolecular Co(II)14-metal-organic cube in a hydrogen-bonded network and a Co(II)-organic framework with a flexible methoxy substituent.
The reaction of 4,5-dicyano-2-methoxyimidazole (L1) with Co(NO3)2·6H2O under solvothermal conditions in DMF, a MOF, and a hydrogen-bonded network consisting of tetradecanuclear Co(ii)14-metal organicExpand
