We synthesized and systematically examined the characteristics of the anthracene single core chromophore material 9-(3',5'-diphenylphenyl)-1'-(3''',5'''-diphenylbiphenyl-4''-yl)anthracene(MAM), the pyrene single core chromophore material 1,6-bis-[1,1';3',1'']terphenyl-5'-yl-pyrene (TP-P-TP), and the dual core chromophore compounds 1-phenyl-6-(10-phenyl-anthracen-9-yl)-pyrene (Ph-AP-Ph) and 1-[1,1';3',1'']terphenyl-5'-yl-6-(10-[1,1';3',1'']terphenyl-5'-yl-anthracen-9-yl)-pyrene (TP-AP-TP). One of the dual core derivatives, TP-AP-TP, exhibited an ELmax value of 456 nm and a high luminance EQE of 7.51% when used in an EL device. The dual core chromophore materials had narrower PL and EL spectra and better thermal properties than the single core chromophore materials. A device based on TP-AP-TP showed twice the lifetime of a device based on the commercialized material, 2-methyl-9,10-bis(naphthalen-2-yl)anthracene (MADN). |
