| 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. |
