Problems solved by technology

In the said document, for example, the charge transport properties of the NO-linking compound (compound 1 on page 63) are evaluated, but there is no description about the production method of materials other than the NO-linking compound. In addition, if the linking element is different Since the electronic state of the compound as a whole is different, the characteristics obtained from materials other than NO-linked compounds are still unknown.

[0581] Under nitrogen atmosphere, put 3,4,5-trichloroaniline (7.0g), 2-bromonaphthalene (22.0g), dichlorobis[(di-tert-butyl(4- A flask of dimethylaminophenyl) phosphino)] palladium (Pd-132, 0.25g), sodium tert-butoxide (NaOtBu, 8.6g) and xylene (130ml) was heated and stirred at 130°C for 1 hour, After cooling the reaction liquid to room temperature, water and ethyl acetate were added and liquid-separated. After washing the organic layer with water, the solvent was distilled off under reduced pressure. Thereafter, the intermediate (A) (15.0 g) was obtained by refining with a silica gel column (eluent: toluene / heptane=1 / 9 (volume ratio)).

Abstract

For example, an organic EL element having an excellent quantum efficiency can be provided by using, as a material for an organic device, a polycyclic aromatic compound as represented by general formula (1) and having a bulky substituent in the molecule. In particular, the device production process is advantaged because concentration quenching can be suppressed even at relatively high use concentrations. In formula (1), R1, R3, R4 to R7, R8 to R11, and R12 to R15 are each independently hydrogen, aryl, and so forth; X1 is -O- or >N-R (R is, e.g., aryl); Z1 and Z2 are a bulky substituent, e.g., aryl; and at least one hydrogen in the compound with formula (1) may be substituted by halogen or deuterium.

Description

technical field [0001] The present invention relates to a material for an organic device having excellent device characteristics derived from a specific structure, an organic electroluminescence device, an organic field effect transistor, and an organic thin film solar cell using the same. Background technique [0002] Previously, various studies have been conducted on display devices using light-emitting elements that perform electroluminescence to achieve power saving or thinning. Furthermore, organic electroluminescent elements containing organic materials are easy to achieve weight reduction and size reduction, so active efforts have been made. Research. In particular, the development of organic materials having light-emitting properties such as blue, which is one of the three primary colors of light, and the development of organic materials having charge transport capabilities such as holes and electrons (with the possibility of becoming semiconductors or superconductor...
