Process for preparing coated organic particles

Abstract

The present invention is in the field of coated organic particles, in particular comprising small molecules, by using atomic layer deposition. It relates to a process for preparing coated organic particles comprising the steps in the following order: (a) bringing particles containing an organic compound in motion to each other, (b) contacting the organic particles with a pretreatment compound in the gaseous state, wherein the pretreatment compound is water, an alcohol or a carboxylic acid, and (c) sequentially contacting the organic particles with a metal-or semimetal-containing compound and a decomposition compound in the gaseous state.
