摘要： An additive for a light-emitting layer contains a compound represented by formula (1): where X is P, C, or S; A is a cyclic hydrocarbon group that may have H, a direct bond, a chain hydrocarbon group, or a heteroatom; R is H or an alkyl group, and a plurality of R may link together to form a ring, and if said ring is formed, at least one R is an alkyl group; m is 0 or 1; r is 1 when X is a phosphorous atom or a carbon atom and 2 when X is a sulfur atom; n is a number represented by 3-m when X is a phosphorous atom, and a number represented by 2-m if X is a carbon atom or a sulfur atom; and p is 1 when m is 0, at least 1 when m is 1, and is a substitutable number in A.

摘要： A light-emitting electrochemical cell has a light-emitting layer and electrodes and disposed on the respective surface thereof. The light-emitting layer includes an organic polymeric light-emitting material and an ionic compound represented by the general formula (1). The ring A1 denotes an aromatic ring; X is S, C or P; R1 denotes R′ or OR′, and R′ denotes an alkyl group; n denotes 0 or 1; B denotes O, OR2 or A2, R2 denotes a saturated hydrocarbon group, and A2 denotes an aromatic ring; the bond a is a single bond or a double bond; the bond a between B and X is a double bond and B is O; when X is P, the bond a between B and X is a single bond and B is OR2 or A2; d is 1 or more; and Y+ denotes a cation.
