Abstract: The present invention is in the field of processes for preparing inorganic metal- or semimetal-containing films. The process comprising (a) depositing a metal- or semimetal-containing compound from the gaseous state onto a solid substrate and (b) bringing the solid substrate in contact with a compound of general formula (I), (II), or (III) in the gaseous state (I) (II) (III) wherein A is NR, NR2, PR, PR2, O, OR, S, or SR, E is N, NR, P, PR, O or S, n is 1, 2, or 3, R is an alkyl group, an alkenyl group, an aryl group, or a silyl group and R′ is hydrogen, an alkyl group, an alkenyl group, an aryl group, or a silyl group, and A, E, and n are chosen such that the compound of general formula (I), (II), or (III) is electronically neutral.

Abstract: The present invention relates to processes for producing microparticles having, in their interior, at least one cavity which is connected via pores to the surface of the microparticles and which have been laden with at least one organic active of low molecular weight. The invention especially relates to a process for loading microparticles with at least one organic active of low molecular weight, wherein the active has been embedded in a matrix and/or the pores of the microparticles have been closed by means of a substance applied to the surface of the microparticles. The invention additionally relates to a process for sealing microparticles laden with at least one organic active of low molecular weight. The invention also relates to compositions of microparticles laden with at least one active of low molecular weight and to the use thereof.
