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) sequentially contacting the organic particles with a first metal- or semimetal-containing com-pound and a first decomposition compound in the gaseous state, and (c) sequentially contacting the organic particles with a second metal- or semimetal-containing compound and a second decomposition compound in the gaseous state, wherein the reaction enthalpy of the reaction of the first metal- or semimetal-containing com-pound with the first decomposition compound is lower than the reaction enthalpy of the reaction of the second metal- or semimetal-containing compound with the second decomposition com-pound.
