英文摘要
The project is devoted to the development of unprecedented non-hydrolytic synthetic methods for the generation of well-defined molecular models of silica and its heavy homologues. Building upon the successful (‘water-free’) synthesis and isolation of the first donor-stabilised monomeric SiX, SiX2 (X = O, S, Se, Te) and Si(CO3)2 complexes, their hydrolysis will be studied to generate Si(OH)4 and related compounds. The suitability of cyclo-Si6Cl12 and its siloxy- and alkoxy-substituted derivatives to serve as molecular models and precursors of oxygen-deficient silicas will further be investigated.
