Title:
Electronic transportation material and the organic electroluminescence element using this
Document Type and Number:
Japanese Patent JP6156487
Kind Code:
B2
Abstract:
The invention concerns a compound represented by formula (1) below, and an organic EL device using the same. The compound of the invention is useful as an electron transport material that contributes to improvement in service life prolongation, reduction of driving voltage, achievement of high efficiency and so forth, above all, improvement in achieving high efficiency, and can provide an excellent organic EL device: wherein, Ar is an m-valent group derived from aromatic hydrocarbon or an aromatic heterocycle; X1 to X6 are ═CR1— or ═N—, at least two of X1 to X6 is ═CR1—, R1 in two of ═CR1— is a bonding hand to be bonded with Ar or an azole ring, and R1 in ═CR1— other than the above is hydrogen or alkyl having 1 to 4 carbons; Y is —O— or —S—; at least one of hydrogen in an azole ring may be replaced by alkyl, phenyl or naphthyl; m is an integer from 2 to 4; and at least one of hydrogen in each ring and alkyl in the formula may be replaced by deuterium.
