Claims13
A dendrimer compound characterized by comprising a core represented by the following formula (1-2) and at least one dendritic structure selected from dendritic structures represented by the following formula (3) or (4):
- wherein unit CD represents an aromatic ring, a metal complex structure, a structure represented by the following formula (5):
- wherein a ring A and a ring B each independently represent an aromatic ring, X represents —O—, —S—, —S(═O)—, —SO2—, —B(R1)—, —Si(R2)(R3)—, —P(R4)— or —PR5(═O)—, and R1, R2, R3, R4 and R5 each independently represent a substituent selected from an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group, an arylalkylthio group, an arylalkenyl group, an arylalkynyl group, an amino group, a substituted amino group and a monovalent heterocyclic group,
- or a structure in which two or more structures selected from an aromatic ring, a metal complex structure and a structure represented by the above formula (5), which may be the same or different, are bonded directly or via a divalent group shown in the following (L-1):
- wherein R′ represents a group selected from a hydrogen atom, an alkyl group, an alkoxy group, an aryl group and an aryloxy group, and when a plurality of R's are present, R's may be the same or different;
- a, b and c each independently represent an integer of 1 to 12;
- and d represents an integer of 1 to 11;
- a unit DA and a unit DB each independently represent an aromatic ring, a metal complex structure, a structure represented by the above formula (5), or a structure in which two or more structures selected from an aromatic ring, a metal complex structure and a structure represented by the above formula (5), which may be the same or different, are bonded;
- at least one of the core and the dendritic structure contains a structure represented by the formula (5),
- and L is a direct bond or a linking group selected from the following (L-2):
- wherein R1′ represents a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aryloxy group, and when a plurality of R1's are present, R1's may be the same or different.
