"Hybrid Inorganic-organic Materials and their Applications"

Inorganic framework materials, such as the aluminosilicate zeolites and the open-framework aluminum phosphates, find widespread applications in separation processes, ion-exchange, and catalysis. During the last 20 years, this field has grown through the discovery of framework materials based upon many other types of chemistries, e.g. oxides, sulfides, halides and nitrides [1]. It has also evolved in another direction with the growing interest in inorganic-organic framework structures, which contain both inorganic and organic components as part of a single framework architecture. Such materials include coordination polymers, in which isolated metal ions or clusters are linked into arrays by organic ligands, and extended inorganic hybrids, such as hybrid metal oxides in which there is M-O-M connectivity in 1-, 2-, or 3-dimensions [2]. They may be nanoporous or dense. The presentation will focus on some aspects of our recent work on framework metal carboxylates. The synthesis of carboxylates with structures of different dimensionalities will be described [3], and we shall examine the factors that control structural trends in hybrid materials, such as ligand geometry, ligand flexibility, synthesis temperature, pH and so on [4-7]. We shall also consider the use of high throughput methods for exploring phase space in hybrid materials [8,9]. Finally, we shall examine some of the applications of hybrid materials in areas such as enantiomerically-selective catalysis, hydrogen storage, and photoluminescence.
