The relationship between the substitution position of the diphenylphosphine oxide on the spirobifluorene and device performances of blue phosphorescent organic light-emitting diodes

A high triplet energy host (SPPO11) with a diphenylphosphine oxide group attached to the 4 position of the spirobifluorene was synthesized and its device performances were compared with those of the triplet host with the diphenylphosphine oxide at the 2 position of the spirobifluorene (SPPO1). The thermal stability of the SPPO11 was much better than that of the SPPO1 and the efficiency of the blue PHOLED with the SPPO11 host was higher than that of the blue PHOLED with the SPPO1 host. The SPPO11 could be effectively used as the high triplet energy host in the blue PHOLED and a high quantum efficiency of 17.2%and a current efficiency of 35.3 cd/A were obtained in the blue PHOLED with the SPPO11 host.

Synthesis and electroluminescence properties of new blue dual-core OLED emitters using bulky side chromophores

Using a 1-anthracen-9-yl-pyrene (AP) dual-core emitter, two new emitters of blue light, 1-spiro-9,9′-bifluoren-4-yl-6-(10-spiro-9,9′-bifluoren-4-yl-anthracen-9-yl)-pyrene (DSF-AP) and 1-[2-(9H-carbazol-9-yl)phenyl]-6-[2-(9H-carbazol-9-yl)phenyl-anthracen-9-yl]-pyrene (DCP-AP), were synthesized through boration and the Suzuki aryl-aryl coupling reaction. These two materials exhibited PLmax values at 443?nm and 448?nm in a chloroform solution, and at 458?nm and 463?nm in a thin-film state. EL devices with the synthesized compounds were fabricated in the following configuration: ITO/4,4′,4″-tris(N-(2-naphthyl)-N-phenylamino)triphenylamine (2-TNATA) (60?nm)/N,N′-bis (naphthalene-1-yl)-N,N′-bis(phenyl)benzidine (NPB) (15?nm)/synthesized blue light-emitting materials (35?nm)/Tris-(8-hydroxyquinoline)aluminum (Alq3) (20?nm)/lithium fluoride (LiF) (1?nm)/Al (200?nm). Compared with the device made using an AP core lacking side groups, the device made with DCP-AP displayed 31% higher luminance efficiency (resulting in a value of 4.37?cd/A) and 32% higher power efficiency (to yield 1.93?lm/W), as well as a high external quantum efficiency (3.64%).
