利用物理喷束淀积 (PJD)技术制备 C60 (CH3) x(PAN) x 共聚物的薄膜。这种共聚物中 ,C60 分子位于星状结构的中心 ,聚丙烯腈 (PAN)主链修饰在 C60 分子的周围。吸收及荧光光谱表明 :C60 分子与聚丙烯腈(PAN)有明显的相互作用 ,而且这种相互作用与 PAN的链长有关。C60 分子与 PAN间存在一定的激发传递过程 ,从而导致 PAN荧光的部分猝灭。
Films of C60 (CH3) x (PAN) x copolymer were prepared by physical jet deposition (PJD) technique. In this copolymer, the C60 molecule is located in the center of the star structure and the polyacrylonitrile (PAN) backbone is modified around the C60 molecule. Absorption and fluorescence spectra show that there is a clear interaction between C60 and polyacrylonitrile (PAN), and this interaction is related to the chain length of PAN. C60 molecules and PAN there is a certain excitation transfer between the process, which led to part of PAN fluorescence quenching.
