Soluble homo and heterometallic coordination polymers based on the oxalate ligand and method for obtaining spinels from them. Homo or heterometallic coordination polymers comprising at least one oxalate ligand are characterised by comprising also at least one organic molecule that can stabilise extended structures of metal complexes by the formation of supramolecular interactions so that this polymer is substantially water-soluble and insoluble in organic solvents. These polymers, when in solid state, can generate spinel-type metal oxides or other mixed oxides after thermal oxidation treatment comprising the steps of preparing an alcohol solution of a metal complex comprising at least one oxalate ligand and a metal salt, precipitate this metal complex and this metal salt with a cryptand-type molecule by formation of a coordination polymer which is water-soluble and insoluble in organic solvents, separate the precipitate obtained in the previous step and heat it under oxidising atmosphere at a temperature of at least 350°C until the spinel or the mixed oxide are formed.

摘要:
The invention concerns non-conjugated luminophor compounds having semiconductor properties, as well as their production and their use in organic light-emitting diodes, organic solar cells, organic photodetectors and organic field effect transistors. Said luminophors are co-polyarylboranes of type K which are transformed, only when a suitable electric field is applied and/or when substituted by the aryl R substituent donor, into a type of structure which acts like a conjugated polymer. The symbols are as defined in Claim 1.
