Synthesis and optical limiting in copolymers of C60 and 1-phenyl-1-butyne
摘要:
While WCl6-Ph4Sn is a poor catalyst for the polymerization of 1-phenyl-butyne (PB) at room temperature, it effectively polymerizes PB in the presence of C60, giving high molecular weight polymers in high yields. The polymer is soluble in THF and chloroform and spectroscopic analysis reveals that C60 has copolymerized with PB. Thus, C60 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 C60.
