Abstract

Several configurationally constrained cis-and trans-1, 2-diaryl-1, 2-dimethyl-1, 2- disilacyclohexanes (3a–e) have been synthesized in order to measure their photophysical properties, such as UV absorption, magnetic circular dichroism (MCD), and photoluminescence. As has been well established, the UV absorption maximum (1 L a band) occurs at 230–270 nm, due to the effective σ–π conjugation between the aryl ...
