摘　　要：A method for the non-destructive purification of single-walled carbon nanotubes(SWNTs)using classical coordination chemistry to remove the metal catalyst has been developed.In preliminary tests,the conductivity of films based on the resulting SWNTs was markedly better than that of films prepared from SWNTs purified by treatment with oxidizing acid solutions.The transparent and conducting SWNT films have potential applications in optoelectronic devices.
