Document Type and Number:
WIPO Patent Application WO/2017/115608
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a π-conjugated compound which is capable of increasing the luminous efficiency of an organic EL element. The present invention is a π-conjugated compound which has a structure represented by one of formulae (1)-(6). (In formulae (1)-(6), each of L and M represents an electron-donating group D or an electron-withdrawing group A; Q represents a carbon atom or a nitrogen atom; the electron-donating group D is an aryl group substituted by an electron-donating group, an optionally substituted electron-donating heterocyclic group, or an optionally substituted amino group; the electron-withdrawing group A is an optionally substituted carbonyl group, an optionally substituted sulfonyl group, an optionally substituted phosphine oxide group, an optionally substituted boryl group, an aryl group which may be substituted by an electron-withdrawing group, an electron-donating heterocyclic group substituted by an electron-withdrawing group or an optionally substituted electron-withdrawing heterocyclic group; and R represents a carbon atom, an oxygen atom, a nitrogen atom, a sulfur atom, a boron atom or a silicon atom.)
