Herein, we report the introduction of a silole unit into cycloparaphenylenes (CPPs), and two compounds [12]Si3CPP [16]Si4CPP are obtained by platinum- gold-mediated cyclooligomerization strategy. Their optical electronic properties studied UV–vis absorption fluorescence spectra, which show red shifts higher photoluminescence quantum yields (PLQYs) compared with corresponding CPPs.
