A supported catalyst having rhodium particles with an average diameter of less than 1 nm disposed on a support material containing magnetic iron oxide (e.g. Fe.sub.3O.sub.4). A method of producing the supported catalyst and a process of reducing nitroarenes to corresponding aromatic amines employing the supported catalyst with a high product yield are also described. The supported catalyst may be recovered with ease using an external magnet and reused.

Octaaminonaphthalene and a method of synthesizing octaaminonaphthalene are described. A two-dimensional coordination polymer and a method of synthesizing the two-dimensional coordination polymer are described. The two-dimensional coordination polymer includes ligands including anchorage sites, and metal linkers, each metal linker including a metal and an organic moiety. Each metal linker is coupled to two ligands via the anchorage sites. Synthesizing the two-dimensional coordination polymer includes contacting a first liquid precursor with a second liquid precursor at an interface, reacting the metal linker and the water-soluble ligand to yield a two-dimensional coordination polymer at the interface, and removing the two-dimensional coordination polymer from the interface.

Compositions of oligoanilines with higher purity, methods of making and using thereof, are provided. The compositions are produced in large scale with larger yield using simple purification techniques such as washing. Methods have been developed that allow large scale synthesis of oligoaniline compounds with the following benefits: (i) higher purity; (ii) larger yield of oligoaniline compounds; (iii) simple purification that does not require complicated techniques such as liquid chromatograph; (iv) lower cost; and (v) full characterization. The highly pure oligoaniline compositions can be used as reducing or oxidizing agent in a redox reaction. The oligoaniline compositions have colors and can be used as dyes, i.e. redox active dyes in a redox reaction, as intermediates for the development of conductive elastomers, or as catalysts.
