In order to achieve special functions in an organic thin film, we have investigated the molecular interaction and arrangement in the adsorption Langmuir-Blodgett (LB) films. Main results are summarized below.1)Remarkable substituent dependence of adsorption phenomena is observed in triphenylmethane derivatives (TPM) adsorbed merocyanine (MC) monolayr.2)The surface pressure and area variations of the MC monolayr during the TPM adsorption are closely related to the monolayr interaction and arrangements between the spreading and adsorbing materials.3) A peculiar properties such as a negative photoelectric effect is observed in the dye-adsorbed LB films.4)The polarized photoabsorption and IR measurements of the adsorption LB films indicate that molecular plane of TPM and MC is normal to the substrate plane and these molecular planes are packed closely each other.These results obtained here demonstrate that the adsorption LB technique is useful for the realization of molecular electronic devices.

为了在有机薄膜中实现特殊功能，我们研究了吸附LB膜中分子间的相互作用和排列。主要结果如下：1）在三苯甲烷衍生物（TPM）吸附汞（MC）的单分子膜中，观察到了显著的取代基依赖性吸附现象; 2）TPM吸附过程中MC单分子膜表面压力和面积的变化与单分子膜间的相互作用以及铺展材料和吸附材料之间的排列方式密切相关。在吸附染料的LB膜中观察到一种特殊的性质，如负光电效应。对吸附LB膜的偏振光吸收和红外光谱的测量表明，TPM和MC的分子平面垂直于基底平面，这些结果表明吸附LB技术对实现分子电子器件是有用的。
