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,
CO.sub.2, 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.
