Methylpolyfluoroalkylsulphides, synthesised by two novel routes: (i) photochemical reaction of a polyfluoroiodoalkane with dimethyl sulphide or dimethyl disulphide and (ii) reaction of a polyfluoroiodoalkane with sodium methanethiolate in the presence of dimethyl disulphide, are useful precursors of polyfluoroalkane-sulphonicacids.

A composition includes a hydroflourothioether represented by the following structural formula (I): Rf-S-Rh (I) Rf is a fluorinated or perfluorinated group having 2-9 carbon atoms and optionally includes one or more catenated heteroatoms or chlorine atoms, and Rh is a non-fluorinated hydrocarbon group having 1-3 carbon atoms. The composition further includes an electroluminescent material.
