Title:
METHOD FOR PRODUCING MATERIAL FOR LIGHT-EMITTING ELEMENTS, MATERIAL PRECURSOR FOR LIGHT-EMITTING ELEMENTS, AND METHOD FOR PRODUCING LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/074428
Kind Code:
A1
Abstract:
Disclosed is a method for producing a material for light-emitting elements, which involves converting a material precursor for light-emitting elements, which is represented by general formula (1) or general formula (2), by heating and/or by means of light irradiation, wherein the resulting material for light-emitting elements contains more trans-forms than cis-forms. Said method can produce, under mild conditions, a material for light-emitting elements, which exhibits excellent durability. (In the formulae, Ar1 to Ar4 may be the same or different from each other, and are selected from among a group consisting of an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, an alkoxy group, an alkylthio group, an arylether group, an aryl thioether group, an aryl group, and a heteroaryl group; however, the substituent group of the abovementioned groups has a configuration in which a cis or trans isomer can exist on the surface of the benzene ring bound to said substituent group. R1 to R24 may be the same or different from each other, are selected from among a group consisting of a hydrogen, a hydroxyl group, an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, an alkoxy group, an alkyl thioether group, an arylether group, an aryl thioether group, an aryl group, and a heteroaryl group, may bind with the neighboring substituent groups, and may form a ring. R1 or R2 and R7 or R8 may bind and form a bicyclic structure, and R13 or R14 and R17 or R18 may bind and form a bicyclic structure.)
