Abstract

Abstract: Molecular building blocks for the preparation of amorphous hybrid organic- inorganic network materials have been synthesized. Hydrolysis and condensation of bis (triethoxysi1yl) aryl 1-4 and-ethynyl 5 monomers results in formation of aryland ethynyl- bridged polysilsequioxanes in the form of xerogels. The gels were glasslike materials composed of uniform aggregates of particles between 50 and 80 nm in diameter. Atomic ...
