▎ 摘　　要

NOVELTY - An organic light-emitting superlattice film is multilayer organic light-emitting film formed by alternate epitaxial growth of 2 two-dimensional organic molecules on surface of a substrate. The two-dimensional organic molecule is perylene-3,4,9,10-tetracarboxylic dianhydride, N,N'-dimethyl-3,4,9,10-perylenetetracarboximide, N,N'-dioctyl-3,4,9,10-perylenedicarboximide and 3,4,9,10-tetraformimide. USE - Superlattice film is used as organic light-emitting layer of field-effect transistor (claimed). ADVANTAGE - The organic light-emitting superlattice film has excellent quality and luminous efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the superlattice film, which involves using growth source material.
