| 摘 要： | Since the discovery of the methods for mass production of fullerenes', there has beengreat interest in the development of fullerene-containing polymeric materials'-' becausesuitably designed fullerene polymers not only possess good processability but also exhibitinteresting materials properties'-'. We have also attached C,o to polyphenylacetylenechains by a WCI,~catalyzed copolymerization reaction'-'. In this letter, we chose anacetylene monomer, that is, l-phenyl-butyne (PB), which can not …

| Abstract: | While WC_16-Ph_4Sn is a poor catalyst for the polymerization of l-phenyl-butyne (PB) at room temperature, it effectively polymerizes PB in the presence of C_(60), giving high molecular weight polymers in high yields. The polymer is soluble in THF and chloroform and spectroscopic analysis reveals that Coo has copolymerized with PB. Thus, C_(60) plays dual roles of comonomer and cocatalyst in the acetylene polymerization. The copolymers strongly attenuate 532-nm laser pulses, whose limiting performance is superior to that of parent C_(60) |
