金属氧化物/聚(N,N-二甲基苯胺)界面相互作用的ESR研究

ESR Study on the Interfacial Interaction Between Metal Oxide and Poly( N,N dimethylaniline)

共轭聚合物在电、光、磁等方面有很大的应用价值［１～３］，利用其研制各种实用性电子器件时，往往会涉及到它与其它材料尤其是无机半导体材料的界面复合问题［４～７］．在这些界面间，除形成一定的化学键外［８］，更多的则是伴随着电子的转移和电荷的重新分配［９，１...

The interfacial interaction between several metal oxides and poly( N,N dimethylaniline)(PDMA) was investigated by ESR. Especially in Fe 2O 3/PDMA system, it is shown obviously that an electron transfer process occurred from nitrogen atoms of PDMA to Fe 2O 3 which made PDMA form more stable radical cations and Fe(Ⅲ) turn into Fe(Ⅱ).
