研究了以低电离能分子为载流子传输层的双层光接收器。电离电势(Lp)由工艺计算和极谱氧化电位估算。CTL的感光性与Lp值之间有很好的相关性。然而，这一结果不能简单地用载流子产生层(CGL)和CTL的能级失配来解释。由于苯乙烯基染料碱、菁染料碱和恶唑类化合物的透明性和在聚合物中的高溶解性，因此选择它们作为CTL材料。使用这些CTL材料的光感受器表现出比众所周知的聚乙烯咔唑-三硝基荧光酮(PVK-TNF)系统更高的灵敏度。由恶唑、OX-2和双偶氮蓝(CDB)组成的体系在650 nm处的光谱灵敏度峰值为0.17m2/mJ。
Double layered photoreceptors using low ionization potential molecules as the carrier transport layer (CTL) have been investigated. The ionization potential (lp) was estimated by the ¿ technique calculation and the polarographic oxidation potential. A good correlation was obtained between the photosensitivity and the lp value of the CTL. However this result could not be explained simply by the energy level misfit of the carrier generation layer (CGL) and the CTL. Styryl dye bases, cyanine dye bases, and oxazoles were selected as CTL materials on the basis of their transparency and high solubility in polymers. The photoreceptors using these CTL materials showed much higher sensitivities than the well-known polyvinylcarbazole- trinitrofluorenone (PVK-TNF) system. The peak value of the spectral sensitivity in the system composed of an oxazole, OX-2, and a disazo pigment, chlorodianeblue (CDB), was 0.17 m 2/mJ at 650 nm.
