TECHNOLOGY FOCUS - ELECTRONICS - Preferred Device: In the device, the photoactive layer comprises a blue luminescent compound, a host material, and the compound (I).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): Preparation of compound (I) involves brominating anthracene compound of formula (i) using bromine (Br2) in carbon tetrachloride solution (CCl4) to give brominated compound of formula (ii); and reacting the compound (ii) with amine and palladium catalyst to give compound (I). Preferred Compound: The compound (I) is compound of formula (II).R2=an electron-withdrawing group;R3=H, D, carbazolyl, diarylamino, an electron-withdrawing group, or a deuterated analog of it;R4 and R5=D, alkyl, alkoxy, silyl, siloxane, an electron withdrawing group, or a deuterated analog of it;c=1-5;d and e=0-4;orc+d=55. Preferred Definitions:    Ar1=phenyl, biphenyl, naphthyl, binaphthyl, phenylnaphthyl, naphthylphenyl, or their substituted derivatives, or deuterated analogs;    R1=D;    R2 and R4=cyano;    R3=carbazolyl, diphenylamino, or their deuterated analog;    d=0 or 1;    e=0.    SPECIFIC COMPOUNDS - 11 Compounds are disclosed as the compound (I), e.g. 3-((3-carbazol-9-yl-phenyl)-(10-(4-naphthalen-1-yl-phenyl)-anthracen-9-yl)-amino)-benzonitrile (Ia), 4-((3-(3,6-diphenyl-carbazol-9-yl)-phenyl)-(10-(4-naphthalen-1-yl-phenyl)-anthracen-9-yl)-amino)-benzonitrile, 5-((3-(3,6-diphenyl-carbazol-9-yl)-phenyl)-(10-(4-naphthalen-1-yl-phenyl)-anthracen-9-yl)-amino)-isophthalonitrile, 5-((3-(biphenyl-4-yl-phenyl-amino)-phenyl)-(10-(4-naphthalen-2-yl-phenyl)-anthracen-9-yl)-amino)-isophthalonitrile, 4,4'-(10-(naphthalen-2-yl)anthracen-9-ylazanediyl)dibenzonitrile.    EXAMPLE - Taking carbazoleanthracene (0.64 g) in glove box and adding bromophenylnitrile (0.36 g), dissolving tris(dibenzylideneacetone)dipalladium(0) (Pd2DBA3) (0.1 g), tri-tert-butylphosphine (P(t-Bu)3) (0.045 g) and sodium tert-butoxide (t-BuONa) (0.25 g) into toluene (25 ml). Heating in glove box in mantle at 80 degrees C under nitrogen for 2 hours. After work-up, 3-((3-carbazol-9-yl-phenyl)-(10-(4-naphthalen-1-yl-phenyl)-anthracen-9-yl)-amino)-benzonitrile ( approximately 0.3 g) was obtained.
