System comprising organic or metallo-organic energy and/or charge variable moieties

The invention relates to a system for use in an elec. or optical device comprising at least two org. or metallo-org. energy and/or charge variable moieties having conjugated unsatd. bonds, wherein at least one moiety has an energy state different from another of said moieties, characterized in that the system is a H-donor-H-acceptor system comprising at least one H-donor mol. having at least two hydrogen bonding clusters, each cluster comprising at least two groups having formed a hydrogen bond, and at least two H-acceptor mols., each having at least one hydrogen bonding cluster, each cluster comprising at least two groups having formed a hydrogen bond with the groups of the H-donor mol., at least one of the H-donor and H-acceptor mols. 10 further comprising one or more of the org. or metallo-org. energy and/or charge variable moieties.
