[0318] When current was applied to the organic light emitting devices manufactured in Experimental Examples 1-1 to 1-16 and Comparative Examples 1-1 to 1-5, the results of the following Table 1 were obtained.
[0319] [Table 1]
[0320]
[0321] As observed in Table 1, it can be seen that when the compounds in Experimental Examples 1-1 to 1-16 are used as an electron blocking layer in an organic light emitting device, the compounds exhibit lower voltage and higher efficiency characteristics than the materials in Comparative Examples 1-1 to 1-5.
[0322] Specifically, when Experimental Examples 1-1 to 1-6 and Comparative Examples 1-1 and 1-4 were compared with each other, it was determined that the case where carbazole was directly substituted at the ortho position of the benzene ring had the effect of reducing the driving voltage by 10% to 15% and increasing the light efficiency by 20%, compared with the case where carbazole was substituted at the meta and para positions of the benzene ring.
[0323] In addition, when Experimental Examples 1-7 and 1-8 and Comparative Examples 1-2 and 1-3 are compared with each other, the case where carbazole is directly substituted at the ortho position shows lower driving voltage and higher efficiency even when there is a linking group (linker) between the benzene ring and the carbazole structure, compared with the case where carbazole is substituted at the meta and para positions. It can be seen that such a trend is shown even in Experimental Examples 1-9 to 1-12 and Comparative Example 1-5 in which the benzene ring is substituted with fused benzocarbazole.
[0324] Therefore, it can be confirmed that the compound derivative according to the chemical formula of the present specification has excellent electron blocking ability and thus exhibits low voltage and high efficiency characteristics and can be applied to an organic light emitting device.

[0375]
[0376] When current was applied to the organic light emitting devices manufactured in Experimental Examples 2-1 to 2-16 and Comparative Examples 2-1 to 2-4, the results of the following Table 2 were obtained.
[0377] [Table 2]
[0378]
[0379] As observed in Table 2, it can be seen that when the compounds in Experimental Examples 2-1 to 2-16 were used as a hole transport layer in an organic light-emitting device, the compounds exhibited lower voltage and higher efficiency characteristics than those in Comparative Examples 2-1 to 2-4.
[0380] Specifically, when Experimental Examples 2-1 to 2-6 and Comparative Examples 2-1 and 2-4 were compared with each other, it was determined that the case where carbazole was directly substituted at the ortho position of the benzene ring had the effect of reducing the driving voltage by 8% to 10% and increasing the light efficiency by 20% to 25%, compared with the case where carbazole was substituted at the meta and para positions of the benzene ring.
[0381] In addition, when Experimental Examples 2-7 and 2-8 and Comparative Example 2-4 are compared with each other, the case where carbazole is directly substituted at the ortho position shows lower driving voltage and higher efficiency even when there is a linking group (linker) between the benzene ring and the carbazole structure, compared with those when carbazole is substituted at the meta position. It can be seen that such a trend is shown even in Experimental Examples 2-9 to 2-12 and Comparative Examples 2-2 and 2-3 in which the benzene ring is substituted by fused benzocarbazole.
