资源简介：
Well-defined π-conjugated systems containing two or three silacyclobutene units have been synthesized in high yields via regioselective coupling of bis(phenylethynyl)silanes with dialkynylbenzene or trialkynylbenzene in the presence of Cp2ZrBun2 (Negishi reagent). The UV−vis absorption and fluorescence spectra of these new π-conjugated systems have demonstrated that the increase in silacyclobutene units per molecule from two or three brings about an increase of the extinction coefficient.
