Abstract
The present invention provides a light emitting device material which enables a light emitting device having high efficiency and excellent chromatic purity and durability using a light emitting device material containing a pyrene compound represented by formula (1), wherein any one of R1 to R10 is a group represented by formula (2), or 1 to 4 substituents is/are group(s) represented by formula (3), and a light emitting device using the same.
Claims11
A light emitting device material containing a pyrene compound represented by formula (1):
- wherein R1 to R10 may be the same or different and represent a group selected from the group consisting of hydrogen, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, an alkoxy group, an alkylthio group, an arylether group, an arylthioether group, an aryl group, a heteroaryl group, halogen, an amino group, a cyano group, a silyl group and —P(═O)—R11, and adjacent substituents may be combined to form a ring structure;
- R11 represents a group selected from among an aryl group and a heteroaryl group, provided that any one of R1 to R10 is a group represented by formula (2) or 1 to 4 substituents is/are group(s) represented by formula (3):
- wherein R12 to R21 may be the same or different and represent a group selected from the group consisting of hydrogen, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, an alkoxy group, an alkylthio group, an arylether group, an arylthioether group, an aryl group, a heteroaryl group, halogen, an amino group, a cyano group and a silyl group, and adjacent substituents may be combined to form a ring structure, B is a boron atom, X is a group selected from among an oxygen atom, a sulfur atom and —NR22—, R22 is a group selected from among hydrogen, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, an aryl group, a heteroaryl group and an amino group, and R22 and R17 may be combined to form a ring.
