We report here the synthesis and growth of nanocyrstalline ZnO particles from solid and the CVS of nanoparticles size < 10nm from siloxy-substituted di-, tri-,tetra- and polynuclear ZnO-clusters. ZnO is of interest for a wide range of applicaticons such as electrodes for solar cells or for electroluminescence devices. The ZnO-aggregates as molecular precursors are accessible by simple reactions of ZnR'2 with the respective silanoles R3SiOH, affording the dimeric [(Me3Si)2NZnOSiR3]2, trinuclear [(MeZn)2Zn(OSiR3)4], tetranuclear heterocubanes [MeZnOSiR3]4 and the polymeric [(Me3SiO)2Zn]n respectively. Surprisingly, they are useful single-source precursors for low-temperature synthesis of ZnO particles in solid state and through chemical vapor synthesis (CVS).
