Problems solved by technology

However, the oxidation-reduction stability of the aromatic ring with a small conjugated system is not sufficient, and the life of the device using the molecule having the conventional aromatic ring as the host material is not sufficient.
On the other hand, polycyclic aromatic compounds with extended π-conjugated systems usually have excellent redox stability, but the HOMO-LUMO gap (band gap Eg of the film) or the triplet excitation energy (E T ) are low and are therefore considered unsuitable for host materials

[1758]

[1759] Under nitrogen atmosphere, intermediate (I-A) (16.0 g), intermediate (I-B) (12.8 g), dichlorobis[(di-tert-butyl(4-dimethylaminophenyl) phosphino)palladium] (Pd-132, 0.29 g), sodium tert-butoxide (NaOtBu, 5.9 g) and xylene (100 ml) were placed in a flask, and heated at 120° C. for 1 hour. After the reaction, water and ethyl acetate were added to the reaction liquid and stirred, and then the organic layer was separated and washed with water. Then, the organic layer was concentrated to obtain a crude product. The crude product was purified with a silica gel short column (eluent: toluene / heptane=1 / 4 (volume ratio)) to obtain Intermediate (I-C) (22.6 g).

Abstract

The present invention provides a novel amino-substituted polycyclic aromatic compound, a reactive compound, a polymer compound, a suspension type polymer compound, and a use using same. Specific aminogroups or specific substituents, such as Ra groups and Rb groups, are introduced into a polycyclic aromatic compound in which a plurality of aromatic rings are linked by boron atoms, oxygen atoms, orthe like, thereby increasing options for organic device materials such as organic EL element materials. In addition, by using such a novel amino-substituted polycyclic aromatic compound as a materialfor an organic EL element, it is possible to provide an organic EL element having, for example, excellent light emission efficiency or element life.

Description

technical field [0001] The present invention relates to an amino-substituted polycyclic aromatic compound and its multimer (hereinafter, also collectively referred to as "polycyclic aromatic compound"), and an organic electroluminescence device, organic field effect transistor and organic thin film using the same Solar cells, display devices and lighting devices, reactive compounds, polymer compounds, suspension-type polymer compounds, and uses using the same. In addition, in this specification, an "organic electroluminescence element" may be expressed as an "organic EL (electroluminescence) element" or only as a "element". Background technique [0002] In the past, various studies have been conducted on display devices using light-emitting elements that perform electroluminescence to achieve power saving and thinning. Further, organic electroluminescent elements containing organic materials have been actively used because they are easy to reduce in weight or increase in siz...
