Abstract: The invention relates to an electroluminescent organic-inorganic hybrid material which is characterised in that it comprises: at least one microporous or mesoporous solid having a structure that is selected from among the structures of zeolites, porous oxides, molecular sieves, silicoaluminophosphates and aluminosilicates; and at least one organic compound which confers electroluminescent properties thereto. The invention is also characterised in that the organic compound is a polycyclic aromatic hydrocarbon, at least part of which is joined to the structure of the microporous or mesoporous solid using covalent bonds. The invention also relates to the method of obtaining said material and to the use thereof.

Abstract: The invention relates to a catalytic composition comprising: a first component which is at least a component with one or more metals from groups 3A, 4A, 5A, 6A, 7A, 8, 1B, 2B, 3B, 4B; and a second component selected from (1) at least one ionic liquid which consists of a compound formed by cations and anions and which is a liquid at ambient temperature, (ii) a matrix to which the first component is bound or on which it is supported, and (iii) a combination of the two. The invention relates to the use of said catalytic composition in a method for the insertion of carbon dioxide into an organic compound and, preferably, a compound selected from epoxides, acetals and orthoesters. The invention also relates to catalytic compositions comprising said metallic compounds.

Abstract: An electroluminescent material comprising at least one electroluminescent compound supported in a matrix, wherein the matrix is selected from among microporous and mesoporous materials, selected from among zeolites, porous oxides, molecular sieves, silicoaluminophosphates and aluminosilicates, the electroluminescent compound is selected from among polymers derived from polyphenylenevinylene, complexes of IIIA group metal ions with 8-hydroxyquinoline and combinations thereof, and where the electroluminescent compound is housed in interior spaces of the matrix. These electroluminescent materials possess excellent properties in terms of chemical stability towards the environment (oxygen, humidity, CO2, etc.), durability (number of electroluminescent cycles under aerobic conditions), control of the state of aggregation (isolated or being associated in pairs or more) of aromatics.
