- An appropriate molecular weight facilitates the formation of the light emitting layer of the organic light emitting device, and an appropriate band gap prevents the loss of electrons and holes in the light emitting layer, thereby helping to form an effective recombination zone.
- the strong hole transfer (HT) characteristic of the substituted arylamine group at that position is a hole blocking (Hole) in the dopant. trap) was confirmed. This could be confirmed through the HOMO / LUMO data of Tables 11 and 12 below.
- a compound in which an electron transport (ET) group is substituted at an appropriate position such as the heterocyclic compound according to the present application, has a lower T1 value than a compound in which an electron transport group is substituted at another position. Since the T1 value of the general red dopant is low, it is determined that energy transfer from the host to the dopant easily occurs, thereby increasing the efficiency.
- the threshold voltage can be adjusted according to the tendency of the electron transfer (ET) group. Specifically, when an amine is substituted in the core structure of the heterocyclic compound according to the present application, the heteroatom of the amine group improves the hole injection ability of the hole transport group, thereby increasing efficiency and lifespan.
- a glass substrate coated with an indium tin oxide (ITO) thin film to a thickness of 1,500 ⁇ was washed with distilled water and ultrasonic waves. After washing with distilled water, ultrasonic washing was performed with a solvent such as acetone, methanol, isopropyl alcohol, etc., dried, and then UVO (Ultraviolet Ozone) treatment was performed for 5 minutes using UV in a UV (Ultraviolet) washer. After transferring the substrate to a plasma cleaner (PT), plasma treatment was performed to remove the ITO work function and residual film in a vacuum state, and then transferred to a thermal deposition equipment for organic deposition.
- ITO indium tin oxide
- the light emitting layer was thermally vacuum-deposited thereon as follows. Specifically, the compounds described in Examples 1 to 9 of Table 13 were used as the red host of the light emitting layer, and 3wt% of the red phosphorescent dopant (piq) 2 (Ir) (acac) was doped into the red host to have a thickness of 500 ⁇ . A light emitting layer was deposited. Thereafter, 60 ⁇ of basocuproine (hereinafter, BCP) was deposited as a hole blocking layer, and 200 ⁇ of Alq 3 was deposited thereon as an electron transport layer.
- BCP basocuproine
- lithium fluoride (LiF) is deposited on the electron transport layer to a thickness of 10 ⁇ to form an electron injection layer, and then an aluminum (Al) cathode is deposited to a thickness of 1,200 ⁇ on the electron injection layer to form a cathode.
- Al aluminum
