Abstract
A compound is represented by the following formula (I): wherein each of Ar1 and Ar2 independently represents an aromatic ring or an aromatic heterocyclic ring; each of R1, R2, R3 and R4 independently represents a hydrogen atom or a substituent; each of Z1 and Z2 independently represents a carbon atom or a nitrogen atom; each of ring Q1 containing a carbon atom and Z1, and ring Q2 containing a carbon atom and Z2 independently represents an aromatic ring or an aromatic heterocyclic ring; and A1 represents a single bond or a divalent linking group.
Claims13
A compound represented by the following formula (II):
- wherein
- each of ring Q5 containing Z15, Z17 and Z19, and ring Q6 containing Z16, Z18 and Z20, independently represents a 5- or 6-membered aromatic ring or aromatic heterocyclic ring;
- each of Z15, Z16, Z17, Z18, Z19 and Z20 , independently represents a carbon atom or a nitrogen atom;
- each of a bond for bonding Z15 to Z17, a bond for bonding Z15 to Z19, a bond for bonding Z16 to Z18, and a bond for bonding Z16 to Z20 independently represents a single bond or a double bond, provided that when Z15 represents a nitrogen atom, each of the bond for bonding Z15 to Z17 and the bond for bonding Z15 to Z19 represents a single bond, and when Z16 represents a nitrogen atom, each of the bond for bonding Z16 to Z18 and the bond for bonding Z16 to Z20 represents a single bond;
- Z17, Z18, Z19 and Z20 do not have a substituent;
- each of ring Q3 containing a carbon atom, Z11 and Z13, and ring Q4 containing a carbon atom, Z12 and Z14, independently represents an aromatic ring or an aromatic heterocyclic ring;
- each of Z13 and Z14 independently represents a carbon atom or a nitrogen atom;
- each of Z11 and Z12 independently represents a carbon atom;
- each of a bond for bonding Z11 to the carbon atom coordinating to Pt contained in ring Q3, a bond for bonding Z11 to Z13, a bond for bonding Z12 to the carbon atom coordinating to Pt contained in ring Q4, and a bond for bonding Z12 to Z14 independently represents a single bond or a double bond,
- Z13 and Z14 do not have a substituent;
- each of R11, R12, R13 and R14 independently represents a hydrogen atom or a substituent;
- and
- A2 represents a single bond or a divalent linking group.
