Abstract
In this project, the bonding properties of silicon were expanded by treating this non-metal/metalloid as a traditional metal for inorganic chemistry. Like carbon, silicon traditionally prefers to form four bonds but can adopt hyper-coordinate configurations. This was achieved in this study through reaction of a ketoimine with sodium hexamethyl silazide followed by reaction with silicon tetrachloride yielding silicon with six bonds. The compound was characterized with 1H NMR and evidence for the structure show was collected. The compound’s electronic properties were investigated with absorbance and fluorescence spectroscopies and the silicon compound showed interesting fluorescence properties. With the development of a general synthetic methodology, another silicon complex with varying electronic properties was prepared and differences in their fluorescence properties were examined.
