Oxygen-containing fused ring amine compound, sulfur-containing fused ring amine compound and organic electroluminescence device

#This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2012-282908, filed on Dec. 26, 2012; the entire contents of which are incorporated herein by reference.

#In an embodiment, the present invention relates to an oxygen-containing fused ring amine compound and a sulfur-containing fused ring amine compound, more in detail, an amine compound having a fused ring comprising a furan ring or a thiophene ring. In another embodiment, the present invention relates to an organic electroluminescence device employing the oxygen-containing fused ring amine compound and/or the sulfur-containing fused ring amine compound.

#Generally, an organic electroluminescence device (organic EL device) is composed of an anode, a cathode, and one or more organic thin film layers sandwiched between the anode and the cathode. When a voltage is applied between the electrodes, electrons are injected from a cathode and holes are injected from an anode into a light emitting region. The injected electrons recombine with the injected holes in the light emitting region to form excited states. When the excited states return to the ground state, the energy is released as light.

#FIG. 1 is a schematic cross-sectional view of an example of the organic electroluminescence device in an aspect of the invention.

#The carbon number of a to b in the expression of “a substituted or unsubstituted X group having a to b carbon atoms” referred to herein is the carbon number of the unsubstituted X group and does not include the carbon atom or atoms of the optional substituent of the X group.

#The definition of hydrogen atom includes isotopes different in the neutron numbers, i.e., light hydrogen (protium), heavy hydrogen (deuterium), and tritium.

#Examples of the optional substituent when saying “substituted or unsubstituted” herein include an alkyl group having 1 to 50, preferably 1 to 10, more preferably 1 to 5 carbon atoms; a cycloalkyl group having 3 to 50, preferably 3 to 6, more preferably 5 or 6 ring carbon atoms; an aryl group having 6 to 50, preferably 6 to 24, more preferably 6 to 12 ring carbon atoms; an aralkyl group composed of an aryl group having 6 to 50, preferably 6 to 24, more preferably 6 to 12 ring carbon atoms and an alkyl portion having 1 to 50, preferably 1 to 10, more preferably 1 to 5 carbon atoms; an amino group; a mono- or dialkylamino group having an alkyl group having 1 to 50, preferably 1 to 10, more preferably 1 to 5 carbon atoms; a mono- or diarylamino group having an aryl group having 6 to 50, preferably 6 to 24, more preferably 6 to 12 ring carbon atoms; an alkoxy group having an alkyl group having 1 to 50, preferably 1 to 10, more preferably 1 to 5 carbon atoms; an aryloxy group having an aryl group having 6 to 50, preferably 6 to 24, more preferably 6 to 12 ring carbon atoms; a mono-, di- or tri-substituted silyl group having a group selected from an alkyl group having 1 to 50, preferably 1 to 10, more preferably 1 to 5 carbon atoms and an aryl group having 6 to 50, preferably 6 to 24, more preferably 6 to 12 ring carbon atoms; a heterocyclic group having 5 to 50, preferably 5 to 24, more preferably 5 to 12 ring atoms and 1 to 5, preferably 1 to 3, more preferably 1 to 2 hetero atoms, such as a nitrogen atom, an oxygen atom and a sulfur atom; a haloalkyl group having 1 to 50, preferably 1 to 10, more preferably 1 to 5 carbon atoms and 1 to 8, preferably 1 to 5, more preferably 1 to 3 halogen atoms, such as a fluorine atom, a chlorine atom, a bromine atom and an iodine atom; a halogen atom, such as a fluorine atom, a chlorine atom, a bromine atom and an iodine atom; a cyano group; and a nitro group.
