富勒烯C_(60)衍生物的合成及其分子沉积膜的制备

Adsorption selfassembly of multilayer films of organic molecules and polyelectrolytes

采用NaOH和发烟硫酸对富勒烯C60进行化学处理,合成了富勒烯磺酸基化合物和羟基化合物,采用红外光谱、紫外-可见光吸收光谱对富勒烯衍生物进行表征,并分别与聚电解质(PDDA)进行了分子沉积膜实验,结果显示富勒烯磺酸基化合物能较好地获得分子沉积膜.

Sulfonic fullerene derivatives and polyhydroxylatde fullerene derivatives were synthesized directly by the reaction of fullerene with NaOH and fuming sulfuric acid, and the properties of the derivatives are studied by means of infrared absorption spectrum(IR) and ultravioletvisible absorption spectrum(UVvis). The experiment of molecular deposition film show that sulfonic fullerene derivatives and poly(diallyldimethyla mmoniumchollride)(PDDA) can well alternatively deposit to get MD film.
