Photoconductivity of poly((E,E)‐6.2paracyclophane‐1,5‐diene) and its complex with TCNE

摘要

AbstractSteady‐state photoconductivity measurements carried out for poly((E,E)‐6.2‐paracyclophane‐1,5‐diene) pure and sensitized with tetracyanoethylene show that doping causes a significant increase of the photoconductivity. This is due to an increase of both the hole mobility and the photogeneration efficiency. The shape of the spectral characteristic is explained by the possible existence of two paths for charge‐carrier photogeneration connected with absorption of the light by the cyclophane unit for shorter wavelengths or by CT complex for longer wavelengths. For an electric field lower than 106V/m, the photocurrent exhibits an ohmic field dependence, and for higher fields, it becomes proporti
