摘    要: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。

关 键 词:富勒烯  共聚物  激发传递  光致发光  聚丙烯腈

Abstract:Thin film of new synthesized C 60(C H 3) x (PAN) x copolymer was fabricated by physical jet deposition (PJD) technique.C 60 molecule lies in the center of the s tar-like copolymers.PAN main chain is modified around the C 60 molecule s.Absorption and photoluminescence spectra show that there are strong interactio n between C 60 molecule and PAN,which depends on the length of PAN chain .Partly excitation transfer process between C 60 molecule and PAN was obs erved,which leads to the fluorescence quenching of the PAN.
Keywords:Fullerene    Copolymer    Excitation transfer    Ph otoluminescence
