Theirelec-tron affinities, measured by cyclic voltammetry, indicated that all these acridone derivatives could be reduced easily and had higher electron affinities than2-(4- biphenyl)-5-( t-butylphenyl)-1,3,4- oxadiazole( PBD) 用循环伏安法测出它们各自的电子势,发现吖啶酮类衍生物都具有较高的电子亲和势,表现出比常用的电子传输材料2-(-联苯基)5-(丁苯基)1,3,4-二唑(BD)容易被还原的优良电化学性能。
Deborah Swackhammer, an ecologist with the University of Minnesota, studied fish in Siskiwit Lake on the island and found concentrations of the toxic chemical polychlorinated biphenyl.
