使用并五苯、1,2-苯并并五苯、1,2,8,9-二苯并并五苯、6,13-二苯基并五苯和5,7,12,14-四苯基并五苯的蒸发薄膜研究了暗电流和光电流的“氧效应”。在暗电流中没有检测到氧效应。根据光电流对氧压力的依赖性以及光电流衰减速率，可以得出结论，表面复合物的光激发在光照下产生了额外的电荷载流子。
The "oxygen effect" on the dark current as well as that on the photocurrent was investigated using thin evaporated films of pentacene, 1,2-benzpentacene, 1,2,8,9-dibenzpentacene, 6,13-diphenylpentacene, and 5,7,12,14-tetraphenylpentacene. No oxygen effect could be detected in the dark current.From the photocurrent dependence on oxygen pressure and from the rate of photocurrent decay, it is concluded that additional charge carriers are produced on illumination by photoexcitation of a surface complex.
