Abstract: The present invention discloses a method for the intercalation of a chromophore within channels of a zeolite L crystal. The intercalated chromophores exhibit J type aggregation of the chromophores within the channels of the zeolite L crystals. The invention discloses method parameters which lead to the J type aggregation of the chromophores within the channels of the zeolite L crystals. The J type aggregation of the chromophores affords unique florescent properties rendering the intercalated zeolite L crystals as a material for use in novel optoelectronic devices.

Abstract: A conjugate comprising a dye-labeled microporous crystal, a stop-cock moiety, and covalently bound thereto an affinity binding agent is disclosed. The dye-labeled microporous crystal is a zeolite crystal, such as a zeolite L crystal, having a large number of channels in its interior into which the dye is loaded. The stop-cock moiety can be functionalized with an amino group to which a carboxyester group can be attached. The affinity binding agent allows for the binding to a biological moiety. The conjugate of the moiety can be used in in-vivo and/or in-vitro imaging applications.

Abstract: A phosphorescent metal complex compound, a method for the preparation thereof and a radiation component, in particular an organic light emitting electrochemical cell (OLEEC) use a bidentate ligand containing a triazole unit. Some of the blue emitters shown here for the first time, in particular the class of iridium complex compounds presented here, are the bluest emitters that have ever existed.

Abstract: Disclosed is a salt of an organometallic complex cation and an organometallic complex anion, wherein the cation as well as the anion consists of a central metal atom M of atomic weight greater than 40 associated to 2 or more ligands, at least one ligand comprising a cyclic organic moiety with a carbon atom bonding to M, and at least one ligand comprising a cyclic organic moiety with a nitrogen atom bonding to M.
