The present invention relates to an anisotropic films and method for obtaining the same. The film comprises substrate and at least one modified conjugated aromatic crystalline layer deposited onto said substrate. The said layer is characterized by globally ordered crystalline structure with intermolecular spacing of 3.4±0.3 Å along one of optical axes. The modified conjugated aromatic crystalline layer is formed by rodlike supramolecules, which comprise at least one polycyclic organic compound with conjugated &pgr;-system. At least part of the modified conjugated aromatic crystalline layer has electric conductivity and is slightly soluble or insoluble in polar solvents. The films are useful in optical applications, such as polarizers and retarders, and in electronic and light emitting devices, such as fiber optics modulators and switches, solar cells, charge-coupled device (CCD), thin film transistor integrated circuits, light emitting diodes, and light emitting displays. The invention features the use of organic compounds for manufacturing thin crystal films useful in various applications.
本发明涉及一种各向异性薄膜及其获得方法。薄膜包括基底和沉积在基底上的至少一个改性共轭芳香族结晶层。所述层的特征是具有全局有序的结晶结构,分子间距沿光轴之一为 3.4±0.3 Å。改性共轭芳香族结晶层是由棒状超分子形成的,这些超分子包括至少一种具有共轭&pgr;系统的多环有机化合物。改性共轭芳香族结晶层的至少一部分具有导电性,并且微溶于或不溶于极性溶剂。这些薄膜可用于光学应用,如偏振器和阻滞剂,以及电子和发光器件,如光纤调制器和开关、太阳能电池、电荷耦合器件(CCD)、薄膜晶体管集成电路、发光二极管和发光显示器。本发明的特点是使用有机化合物制造各种应用中有用的晶体薄膜。
