<p>PROBLEM TO BE SOLVED: To obtain a compound material useful as an optical function material, sufficiently stabilized by a simple treatment without impairing essential functions of an organic compound, by bringing an inorganic laminar compound into contact with an organic guest molecule in the presence of carbon dioxide in a supercritical state. SOLUTION: An inorganic laminar compound (preferably montmorillonite) in an amount of 100 pts.wt. and an organic guest compound (e.g. 4phenylazoaniline) in an amount of 1-5 pts.wt. are fed to a pressure container and are liquefied by introducing carbon dioxide while cooling the container. The compounds are made into a supercritical state at 30-50 deg.C under 10-20 Mpa, retained for at least one hour while being brought into contact with each other. Then the pressure is reduced and carbon dioxide is removed to give the objective compound material with the proviso that the organic guest compound having dissolved carbon dioxide is transported to every nook and corner of the fine voids of the inorganic laminar compound and uniformly adsorbed on every parts of the voids and strongly retained.</p> |
