Abstract: An aromatic composition comprises aromatic substances that are encapsulated and/or clathrated in a matrix of polymer. The polymer includes an inorganic polymer produced from metal alkoxides; a conjugated polymer produced from metal alkoxides and silane coupling agents; and a conjugated polymer produced from metal alkoxides, silane coupling agents, and organic monomers. The aromatic composition has slow-release characteristics, so that the aromatic substances are released over a long period of time. In a method for the production of the aromatic composition, a catalyst for sol-gel methods that comprises an acid or its anhydride and an organic base, and if necessary, irradiation with ultraviolet light and/or an electron beam are used for making the polymer.
