Abstract

The invention provides an organic micro-molecular film containing protonized nitrogen atoms and a preparation method thereof, belonging to the technical field of organic photoelectric materials. The structural formulae of the organic micro-molecular film are shown in the following figure, wherein R1, R2, R3 and R4 represent any structural formula selected from four structural formulae as shown in the following figure. The organic micro-molecular film prepared by the preparation method using the constant-potential or constant-current electrodeposition method has a uniform surface and consists of nano-particles or lamellar crystal without oxidation products; the shape and thickness of the organic micro-molecular film can be controlled by regulating the electrolyte concentration, working voltage, working current and deposition time; and meanwhile, the preparation method of the invention has the advantages of low energy consumption, easily controllable operation and low cost, so the invention is suitable for industrialized production.

Description

technical field [0001] The invention relates to a product in the technical field of photoelectric materials and a preparation method thereof, in particular to an organic small molecule film containing protonizable nitrogen atoms and a preparation method thereof. Background technique [0002] Nitrogen-containing aromatic heterocycles are often introduced into conjugated molecules with photoelectric properties to adjust the size of molecular energy systems and improve the charge conductivity, photophysical and photochemical properties of molecules. Conjugated molecules with nitrogen-containing aromatic heterocycles are widely used in fields such as field-effect transistors, light-emitting diodes, and solar cells. Applications in these fields require the preparation of thin films with excellent photoelectric properties. The traditional method for preparing such molecular films is vacuum evaporation, such as the method for preparing organic electroluminescence elements using nit...
