Abstract:
1. A dendrimer compound characterized by comprising a core represented by the following formula (1-3) and at least one dendritic structure selected from dendritic structures represented by the following formula (3) or (4): wherein a unit CA 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)—, —SO 2 —, —B(R 1 )—, —Si(R 2 )(R 3 )— or —PR 5 (═O)—, and R 1 , R 2 , R 3 , R 4 and R 5 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 W 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); L is a direct bond or a linking group selected from the following (L-2): wherein R 1 ′ represents a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aryloxy group, and when a plurality of R 1 's are present, R 1 's may be the same or different; and at least one of the core unit and the unit in the dendritic structure has a metal complex structure; and wherein the central metal of the complex is selected from the group consisting of aluminum, zinc, beryllium, ruthenium, rhodium, iridium, platinum, gold, europium, and terbium.
