Synthesestrategien zur Darstellung von unterschiedlich funktionalisierten Cyclosiloxanen sowie Addirategy of assembling difunctional entities. The actual progress in this field is reviewed. Furthermore, polysiloxanes are described in which at distinct locations the silicon atoms are replaced by aluminum to which hydroxide groups are attached. The central molecule of interest has the formula [(Ph.

Structure Determining Effect of Alcohols and Water on the Shape of the Hydrogen Bonded Network in Aanol, methanol, and water determine the morphology of the resulting hydrogen bonded network. Thus, incorporation of ethanol/water or methanol, respectively, leads to the tubular structures ..EtOH.H2O . and ..2MeOH ., whereas the incorporation of water alone results in the double sheet structure . .

Silsesquioxane Chemistry II. Tin(IV) and Hafnium(IV) Compounds of Silsesquioxanes,d spectroscopic methods. The results show that complexes containing an organotin(IV) moiety and the ligand in a 1:1 ratio are formed. FTIR spectra are consistent with the presence of Sn-0 vibrations in the compounds. The structure of the complexes is discussed on the basis of . and multinuclear (.H,

Photolumineszenzeigenschaften von substituierten Silsesquioxanen der Zusammensetzung R,(SiO,),,xane (R.(SiO.). n = 6, 8, 10, 12) mit verschiedenen Liganden . untersucht. Alle Silsesquioxane zeigen eine Photolumineszenz im blauen Spektralbereich, deren Intensität und Spektralverteilung von der Käfiggröße . sowie von der Größe und Elektronegativität der Liganden abhängig sind. Als Mechanismus d
