Claim:
A metal complex of formula (II) wherein: M is Ir(III) or Pt(II); J is a mono- or dianionic ligand, which is optionally mono- or bidentate; K is an uncharged, mono- or bidentate ligand; o is 1, 2, or 3 when M is Ir(III) and is 1 or 2 when M is Pt (II); p is 0, 1, 2, 3, or 4 when M is Ir(III) and is 0, 1 or 2 when M is Pt(II); and p is a number of bonding sites to the metal atom M; q is 0, 1 or 2 when M is Ir(III) and is 0 when M is Pt(II); and q is the number of bonding sites to the metal M; wherein a sum of o, p, +q is 3, 4 or 5 when M is Ir(III) and a sum of o+p is 2 or 3 when M is Pt(II), Y 5 and Z 4 are each independently CR 1 , CH, or N; X 2 , X 3 , Y 2 , and Y 3 are each independently N or C; X 4 and X 5 are each independently CR 1 , CH, or N; Y 4 and Y 6 are each independently CR 1 , CH, or N, whereby Y 4 or Y 6 , in the case that m=0, is optionally NR 1 , S, or O; Z 1 , Z 2 , and Z 3 are each independently CR 1 , CH, or N; whereby Z 1 , Z 2 , or Z 3 , in the case that n=0, is optionally NR 1 , S, or O; R 1 is independently an unsubstituted or substituted alkyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted heterocycloalkyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, unsubstituted or substituted alkenyl, unsubstituted or substituted cycloalkenyl, unsubstituted or substituted alkynyl, SiR 2 3 , halogen, a substituent with donor or acceptor action selected from the group consisting of an alkoxy radical, an aryloxy radical, an ester radical, an amino group, an amide radical, a CH 2 F group, a CHF 2 group, a CF 3 group, a CN group, a thio group, a sulfonic acid group, a sulfonic ester group, a boronic acid group, a boronic ester group, a phosphonic acid group, a phosphonic ester group, a phosphine radical, a sulfoxide radical, a sulfonyl radical, a sulfide radical, a SR 3 , a nitro group, OCN, a boran radical, a stannate radical, an imino group, a hydrazine radical, a hydrazone radical, an oxime radical, a nitroso group, a diazo group, a phosphine oxide group, a hydroxyl group, and an SCN group; in addition, two R 1 radicals together may form an alkylene or arylene bridge; R 2 is independently an unsubstituted or substituted alkyl, unsubstituted or substituted aryl, or unsubstituted or substituted heteroaryl; m and n are each independently 0 or 1, whereby Z 4 and Y 5 are absent when n and m=0.
