2.The products obtained by co-heating carbon containing carbyne moieties and element (sulfur) were characterized by elemental analysis, ~(13)C NMR, Raman, and DSC/TG, and the product obtained at 300 ℃ was proved to have a sp~(2) hybride carbon skeleton with polysulfide attached on it, which resembles the theoretical structure of carbyne polysulfide.
