APPLICATION OF POLYGERMANES TO ORGANIC PHOTOCONDUCTOR

研究了聚日耳曼的合成、物理性质及其在光导体中的应用。(1)合成了适合于研究带隙、光学和电学性质的不同分子量的聚日耳曼；(2)聚锗薄膜的物理性质。(3)通过飞行时间（TOF）技术测量注入载流子漂移迁移率（10^<-5>-10^<-7> cm^2/V.s）。(4)用脉冲辐射分解技术研究低聚日耳曼和多聚日耳曼的自由基阳离子（紫外-可见区和红外区两个瞬态吸收带）。(5)聚乙烯薄膜的光化学和热学研究。

Syntheses, physical properties, and applications of polygermanes to photoconductor were investigated. Research results are floated by(1) Synthesis of various molecular weight polygermanes which are suited for investigation of band gap, optical and electrical properties.(2) Physical properties of polygermane thin films.(3) Injected carrier drift mobilities measured by the time-of-flight (TOF) technique (10^<-5>-10^<-7> cm^2/V.s).(4) Study of radical cations of oligogermanes and polygermanes by pulse radiolysis technique (two transient absorption bands in the UV-Vis and IR regions).(5) Photochmeical and thermal studies of polygerman ethin films.
