Zusammenfassung: | The present invention provides: a phenanthroline compound from which it is possible to obtain excellent electron injection ability and electron transportation ability when used in an electron injection layer of an organic electroluminescent element; and an organic thin film obtained from said compound. The present invention pertains to a phenanthroline compound represented by general formula (1). (In general formula (1): R1a-R1d each independently represent a hydrogen atom, an aromatic hydrocarbon group optionally having a substituent group, or an aromatic heterocyclic group optionally having a substituent group; R2a and R2b each independently represent a dialkylamino group that optionally have a substituent group and optionally form a ring structure; R3a and R3b each independently represent a hydrogen atom, an aromatic hydrocarbon group optionally having a substituent group, an aromatic heterocyclic group optionally having a substituent group, -R4=R5-R6 (R4 and R5 each represent CH or N, and R6 represents a hydrogen atom, an aromatic hydrocarbon group optionally having a substituent group, or an aromatic heterocyclic group optionally having a substituent group), -R7-R8 (R7 represents CH2, NH, O, or S, and R8 represents a hydrogen atom, an aromatic hydrocarbon group optionally having a substituent group, or an aromatic heterocyclic group optionally having a substituent group), or a fused ring structure in which R3a and R3b are bound; and at least one of R1a-R1d, R3a, and R3b is an aromatic hydrocarbon group optionally having a substituent group, or an aromatic heterocyclic group optionally having a substituent group.)
La présente invention concerne : un composé de phénanthroline à partir duquel il est possible d'obtenir une excellente capacité d'injection d'électrons et une excellente capacité de transport d'électrons lorsqu'il est utilisé dans une couche d'injection d'électrons d'un élément électroluminescent organique ; et une couche mince organique obtenue à partir dudit composé. La présente invention concerne un composé de phénanthroline représenté par la formule générale (1). (Dans la formule générale (1) : R1a-R1d représentent chacun indépendamment un atome d'hydrogène, un groupe hydrocarboné aromatique ayant éventuellement un groupe substituant, ou un groupe hétérocyclique aromatique ayant éventuellement un groupe substituant ; R2a et R2b représentent chacun indépendamment un groupe dialkylamino qui a éventuellement un groupe substituant et forment |
