✦ Synopsis

The application of matrix-assisted laser desorption time-of-flight mass spectrometry for the analysis of silsesquioxanes is demonstrated. Several matrices have been tested for their utility in combination with a UV-laser based system, of which 2,5-dihydroxybenzoic acid provided the best signal to noise ratios. The technique is also applied to the study of a tungsten derivative of such a compound, and confirms the NMR data which show evidence for the presence of a bis(silsesquioxane)-tungsten complex.
