Paragraph 0195; 0196; 0198, (2017/10/28)
The present invention relates to a compound represented by following general formula (I): wherein R1 and R2 are independently selected from a substituted or unsubstituted C4 to C30 arylamine group, a substituted or unsubstituted C4 to C40 carbazole group, a substituted or unsubstituted C4 to C40 benzothiophene group or a substituted or unsubstituted C4 to C40 benzofuran group; L is a bridging group, and selected from a single bond substituted C4 to C40 arylamine group, a substituted C4 to C40 carbazole group, a substituted C4 to C40 benzothiophene group, O atom, N atom or S atom; R3-R10 are independently selected from H atom, a C1-C20 aliphatic compound containing linear or branched alkanes, alkenes or alkynes or a C6-C30 aromatic group, or two adjacent groups linking to be a ring forming a naphthothiophene derivatives; m and n are selected from integers of 1 to 3, as well as the addition of m and n is larger than 0 but less than or equal to 3. Also, the present invention relates to organic electroluminescent devices using the compound represented by general formula (I), especially a hole transporting material, a hole injecting material or a main material of organic luminescent material used in an OLED device.

Paragraph 0130-0133; 0135, (2016/10/09)
The present invention refers to type (I) as relates to compounds to be represented by, state and used in the R 1 and R 2 in an independently a substituted or unsubstituted C 4-C 30amine it will be biting of, a substituted or unsubstituted C 4-C 40 for dozing, , a substituted or unsubstituted C 4-C 40 of benzo mote five pen or a substituted or unsubstituted C 4-C 40 of benzo [...] and, selected from a, L is the bridging group, single joined, C 4-C 40 of substituted arylamine, C 4-C 40 carbazole-substituted, C 4-C 40 substituted benzothiophene, oxygen atoms, nitrogen atoms or sulfur and one selected from nuclear reactor, R 3-R 10 independently H atoms, C 1-C 20 aliphatic straight or branched chain hydrocarbon groups or C 6-C 888000081488 8 selected from aromatic group or two groups is connected adjacent the upper end the ring form a derivatives [...] , m, integer of at 0-3 graphical object is selected from the n, 3 the m+n less than or equal is greater than 0. The present invention refers to in addition said types of compound use in organic electroluminescence device protects the material exhibits hole-transporting by performing a polishing process in particular OLED, hole injection material or organic light-emitting material protection a main composition.
