金属钼催化C60和苯乙炔共聚物合成及光限幅性能的研究

合成表征了Ｃ６０和苯乙炔共聚物。详细地测试了聚合物溶液的光限幅性能。研究结果表明随溶液浓度增加。聚合物光限幅性能增加，聚合物溶液透射率为６３％时，在低人射激光光强时，航向光强度随人射光强度增加而增加；当入射光强度达４．６Ｊ／ｃｍ＾２透射光强开始偏离线性，随着入射光强进上步增加，透射光强逐渐达到一个饱和值，当入射光强为７．４Ｊ／ｃｍ＾２时，透射光强度几科不再随入射光强度增大而增加，接近一个阈值（０．

Optical Limiting Properties and Synthesis of C60 and Phenylacetylene Copolymer Catalyzed by MoCl5/Ph4Sn

In the paper, the copolymer of C 60 and phenylacetylene with C 60 of 6.9 wt % was synthesized and its structure was charcterized. The optical limiting properties from the polymers in THF solution were studied. The results indicated that the polymer solution with transmittance of 63% (C = 8x10 -4 g/L) exhibited excellent optical limiting properties with output amphitude energy of 0.94 J/cm 2 while homopolyphenylacetylene has no optical limiting properties under the same condition. The amphitude energy increase with the increasing of the solution concentrations. The optical limiting behavior appears to originate from reverse saturable absorption and shows that the copolymer is promising material for optical limiter.
