TECHNOLOGY FOCUS - ELECTRONICS - Preferred Device: In the organic light emitting device, the organic material layers contains a light emitting layer, and the light emitting layer comprises the anthracene derivative (I). The organic material layers contain at least one selected from a hole injecting layer, a hole transporting layer, and an electron transporting layer.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): The anthracene derivative containing thiophene (I) is prepared by using an aryl-aryl coupling method using bromobenzene, substituted heterocyclic group and anthracene boronic acid. Preferred Definitions:    R1-R6=93 compounds as given in the specification e.g. phenyl, naphthyl, biphenyl, terphenyl, anthracenyl (all optionally substituted with at least one of 1-20C alkyl, 1-20C alkoxy (both optionally substituted), cyano, nitro, formyl, (hetero)aryl, 4-7C cycloalkenyl, aryloxy, 1-20C alkylamine, arylamine, alkylarylamine, 1-20C silyl, arylsilyl, alkylarylsilyl, 1-20c alkylboranyl, arylboranyl, alkylarylboranyl, 1-20C alkylthio or arylthio groups), methyl, ethyl, isopropyl, tertiary-butyl, ethenyl, propenyl, 2-methyl-ethenyl, 2-methyl-propenyl, imidazolyl, thiazolyl, oxazolyl, 2-methylimidazolyl, 2-methylthiazolyl, 2-methyloxazolyl, methoxy or ethoxy;    L1=direct bond, phenyl, naphthyl or carbazole;    L2=phenyl, naphthyl or anthracenyl.    SPECIFIC COMPOUNDS - 70 Compounds are specifically claimed as the compound (I), e.g. 2-(3-(10-naphthalen-2-yl-anthracen- 9-yl)-phenyl)-5-phenyl-thiophene (Ia), 2-(3-(10-naphthalen-1-yl-anthracen-9-yl)-phenyl)-5-phenyl-thiophene, 2-phenyl-5-(3-(10-(4-(2-phenyl-eth-(Z)-ylidene)-3-prop-2-en-(Z)-ylidene-cyclohexa-1,5-dienyl)-anthracen-9-yl)-phenyl)-thiophene, 2-phenyl-5-(3-(10-(4-((E)-4-phenyl-but-3-en-(Z)-ylidene)-3-prop-2-en-(Z)-ylidene-cyclohexa-1,5-dienyl)-anthracen-9-yl)-phenyl)-thiophene, and 9-(4-(10-(3-(5-phenyl-thiophen-2-yl)-phenyl)-anthracen-9-yl)-phenyl)-9H-carbazole.    EXAMPLE - 9-(3-Bromo-phenyl)-10-(4-eth-(Z)-yl idene-3-prop-2-en-(Z)-ylidene-cyclohexa-1,5-dienyl)-anthracene (1 g), 5-phenyl thiophen-2-boronic acid (0.53 g) and Pd(PPh3)4 (0.13 g) were dissolved in anhydrous tetrahydrofuran (50 ml), and a 2M aqueous K2CO3 solution (50 ml) were added to it, and then the mixture was refluxed under stirring for 3 hours. After work up, 2-(3-(10-naphthalen-2-yl-anthracen-9-yl)-phenyl)-5-phenyl-thiophene yield 80%) was obtained.
