##STR00001##

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.

[Problem]

An object of the present invention is to provide a compound suitable for a low refractive index layer in a capping layer in order to improve the light extraction efficiency of an organic EL device.

[Solution]

The present invention was achieved by focusing on the fact that an adamantane compound has excellent thin film stability and finding that an amide compound, an ester compound, an amine compound, or an ether compound, in which adamantane is arranged at the center, exhibits a low refractive index property, and an organic EL device having excellent luminous efficiency was obtained by using this compound as a material for forming a capping layer having a low refractive index.
