Title: ELECTROCHEMICAL LIGHT EMITTING CELL
Abstract:
Provided is an electrochemical light emitting cell which is provided with a light emitting layer 3, a first electrode 1 and a second electrode 2, and wherein: the light emitting layer contains an ionic compound; and the ionic compound contains an anion having a silicon atom. The anion comprises, for example, a silicon-containing group represented by SiR1R2R3 (wherein all of the R1-R3 moieties are directly bonded to Si) and an anion group. The anion group is represented, for example, by -SO3-, -OSO3- or -OP(OR0)O3-. Each of the R0-R3 moieties independently represents an alkyl group having 1-4 carbon atoms. Two moieties selected from among the R1-R3 moieties may combine with each other and form an alkylene group having 4 or 5 carbon atoms, said alkylene group constituting a ring structure together with a silicon atom.
