Abstract

Sol–gel (SG) processing of tetraethylorthosilicate is shown to produce porous SiO₂ nano-composites and coatings that contain a variety of adsorbed-impregnated and encapsulated macrocycles. Their texture, cation uptake and spectroscopic properties have been probed. Consideration has been given to whether this technology can be combined to form a sensitive sensor for ions in aqueous solution. The synergy and interaction between the guest and host in these nano-composites will have to be fully explored if this technology is to achieve its full potential in medical and environmental fields.
