Organic light-emitting device and organic photosensitive device using methods, multi-layered crystalline organic thin film structure, it used to form a multi-layer organic thin film crystal structure that has been ordered

摘要

To provide an improved method for growing a crystal of a multi-layer organic film having a desired crystal structure for use in the present invention relates optoelectronic devices. Crystalline organic thin film multilayer structure is [SOLUTION] ordering is formed by depositing a continuous thin film crystalline organic material of at least two layers. Within ± 50% of each other, and, preferably, a thin film layer of the two, is selected to have a surface energy of less than ± 15% of each other at least. Each thin film layer of multilayer organic thin film crystal structure shows a quasi-epitaxial relationship between the crystal organic thin film adjacent to each other.
