Document Type and Number:
WIPO Patent Application WO/2012/173011
Kind Code:
A1
Abstract:
An organic electric-field light-emitting element using the compound shown in general formula (I) emits blue light, and the change in chromaticity during brightness modulation is small (n1 is an integer of 0-8; R1 is a substituent substituted for each of the individual hydrogen atoms of a pyrene structure; X is either CRaRb (Ra and Rb individually are either hydrogen atoms or a substituent) or O,S,SiRdRe (Rd and Re individually are either hydrogen atoms or a substituent); and A1 to A4 individually are either CRf (Rf is either a hydrogen atom or a substituent, and the two adjacent Rf atoms may together form a saturated or unsaturated ring, but there are two or fewer rings formed by two or more Rf atoms together) or N).
