TECHNOLOGY FOCUS - ELECTRONICS - Preferred Layer: The organic layer consists of a hole-injection layer (EE), a hole-transport layer (DD), a light-emitting layer (CC), and an electron-transport layer (BB), containing the anthracene derivative.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No general preparation given. Preferred Compound: The anthracene derivative is preferably of formula (2 or 3).Ar4,Ar5,Z1=H, deuterium, tritium, optionally substituted 1-20C alkyl, optionally substituted 2-20C alkenyl, optionally substituted 2-20C alkynyl, optionally substituted 3-20C cycloalkyl, optionally substituted 3-20C heterocycloalkyl, optionally substituted 6-20C aryl, or optionally substituted arylamino;andZ=H, deuterium, tritium, aryl, or heteroaryl. Preferred Definitions:    Ar1=group chosen from groups of formulae (a-c);    Ar4,Ar5=deuterium, tritium, 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 3-20C cycloalkyl, 3-20C heterocycloalkyl, 6-20C aryl, or arylamino;and    R2=H, deuterium, tritium, optionally substituted 1-20C alkyl, optionally substituted 2-20C alkenyl, optionally substituted 2-20C alkynyl, optionally substituted 3-20C cycloalkyl, or optionally substituted 3-20C heterocycloalkyl.    SPECIFIC COMPOUNDS - 297 Anthracene derivatives are specifically claimed e.g. 4',5'-di-naphthalen-2-yl-9,10-diphenyl-(2,9')bianthracenyl of formula (A), 9,10,4',5'-tetraphenyl-(2,9')bianthracenyl, 4',5'-bis-biphenyl-4-yl-9,10-diphenyl-(2,9')bianthracenyl, 10-naphthalen-1-yl-1,8-diphenyl-anthracene, and 4',5'-di-naphthalen-1-yl-9,10-diphenyl-(2,9')bianthracenyl.    EXAMPLE - (In g) 1,8-di-naphthalen-2-yl-anthracene (7.96) was mixed with chloroform (400 mL) and N-bromosuccinimide (3.3) for 12 hours at room temperature. The obtained solid was filtered after reaction completion, washed with distilled water, and dried to obtain 10-bromo-1,8-di-naphthalen-2-yl-anthracene (5) with a yield of 55%. 10-Bromo-1,8-di-naphthalen-2-yl-anthracene (5), 2-(9,10-diphenyl-anthracen-2-yl)-4,4,5,5-tetramethyl-(1,3,2)dioxaborolane (4.9), and tetrakistriphenylphosphine palladium (0.3) were added to 2M aqueous solution (80 mL) of potassium carbonate and tetrahydrofuran (200 mL) under nitrogen atmosphere, and reflux-stirred for 12 hours. After reaction completion, the mixture was cooled to room temperature. The organic layer was separated and filtered to obtain a solid. The solid was recrystallized using tetrahydrofuran and ethanol, to obtain 4',5'-di-naphthalen-2-yl-9,10-diphenyl-(2,9')bianthracenyl (5.2) of formula (A), with a yield of 70%. An organic electronic device obtained using the compound had excellent efficiency, brightness, responsivity, contrast and stability, low operating voltage, and wide viewing angle.
