给出了一个模型，表明紧密堆积的有机层，吸附在导电基板上的电子性质，可能是非常不同的单个吸附分子的性质。这种差异是由于在衬底和层之间产生电子转移的协同效应引起的。当具有偶极矩和低极化率的分子被组织成使得它们的偶极矩垂直于表面时，它被诱导。热力学的问题进行了说明。该模型提供了一个可能的合理化最近观察到的新的实验性质的吸附有机层。(C)2003 Elsevier B.V.保留所有权利。
A model is given that shows that the electronic properties of close packed organized organic layers, adsorbed on conductive substrate, may be very different from the properties of the single adsorbed molecule. The difference arises from a cooperative effect that results in electron transfer between the substrate and the layer. It is induced when molecules having dipole moment and low polarizability are organized so that their dipole moment is perpendicular to the surface. The thermodynamics of the problem is described. The model provides a possible rationalization to recent observed new experimental properties of adsorbed organized organic layers. (C) 2003 Elsevier B.V. All rights reserved.
