摘要
Recent advances in experimental techniques have led to more stable and reliable all-organic electronic devices as displays, rectifiers and transistors. However, a true molecular device has not yet been realized. In the present work we propose a new type of all-organic transistor with novel properties that is within the feasibility of the present technology for organic materials. Based on molecular modeling techniques, we demonstrate that the conductivity of a conjugated polymer chain may be modulated by a static electric field, without chemical doping. This is the first theoretical characterization of an all-organic molecular transistor based on quantum chemical calculations.
