Thermally activated delayed fluorescence of N-phenylcarbazole and triphenylamine functionalised tris(aryl)triazines
N-phenyl carbazole and triphenylamine functionalized tris(aryl)triazines, as well as the corresponding mononers, have been synthesized by Suzuki cross-coupling reactions. The electronic, photophysical and electrochemical properties of these materials can be effectively tuned by manipulation of the constitution of acceptor and donor units. N-phenyl carbazole and triphenylamine functionalized 2,4,6-trisphenyl-1,3,5-triazines exhibit small energy gaps between the singlet and triplet (0.24 eV and 0.18 eV), and offer potential for application as thermally activated delayed fluorescence materials. The results are supported by time-dependent density functional theory calculations, delayed and time-resolved fluorescence data.

Multiple Electrophilic C-H Borylation of Arenes Using Boron Triiodide
Electrophilic C-H borylation of arenes using boron triiodide has been developed. This reaction proceeded smoothly in the absence of additives, and the diiodoboryl group was installed at the most sterically accessible carbon, where the HOMO is localized to a certain extent. Moreover, regioselective multiple borylation of polycyclic aromatic compounds was achieved by using excess boron triiodide. The borylated intermediates were transformed into a variety of arylboron compounds such as arylboronates, boronic acids, and trifluoroborates.

Blue light emission of new anthracene derivatives produced using optimized side group link positions
Using an anthracene chromophore as a core group and a phenyl carbazole chromophore as a side group, three new emitters of blue light, 2-DCPA, 3-DCPA and 4-DCPA, were synthesized. The three compounds differed with regard to the position of the carbazole linked to the core, with 2-DCPA and 4-DCPA using carbazole nodes and 3-DCPA using the lobe position. Density functional theory calculations were performed to determine which positions of the carbazole moiety had node characteristics and which had lobe characteristics. The PLmax values of 2-DCPA, 3-DCPA and 4-DCPA in the film state were in the blue region, at 453, 457, and 452 nm, respectively. Of these materials, 3-DCPA, i.e., that with the linkage to the lobe position, showed the highest efficiency, with a value of 2.91 cd/A, and EQE, with a value of 2.65%. In a doped device using CBP as a host material and 3-DCPA as a dopant, the ELmax emission was observed to be in the deep blue region, at 433 nm, and with a CIE value of (0.150, 0.068).

New high triplet-energy host materials, which are symmetrically or asymmetrically designed by using phenylcarbazole and thiophene moieties, were synthesized by Suzuki-Miyaura cross-coupling reactions and their device performances of blue phosphorescent organic light-emitting diodes were also investigated. The synthesized compounds showed a high triplet energy (>2.84 eV) and good thermal stability. Highly efficient blue PHOLEDs were obtained when employing the symmetric compounds having C2 symmetry as the host material and bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato)iridium(III) (FIrpic) as the guest material.

Highly efficient and stable deep-blue emitting anthracene-derived molecular glass for versatile types of non-doped OLED applications
New anthracene-based deep-blue emitting molecular glass, 9-(9-phenylcarbazole-3-yl)-10-(naphthalene-1-yl)anthracene (PCAN), which is asymmetrically functionalized with N-phenylcarbazole and naphthalene, has been designed, synthesized, and characterized. The deep-blue emitting PCAN is efficiently secured for color purity, has high glass transition temperature (Tg = 151 °C), and has excellent solubility (>100 mg mL -1 in toluene), due to its highly tilted asymmetric molecular conformation. Using processing versatility of PCAN, vacuum-deposited and solution-processed non-doped deep-blue fluorescent organic light-emitting diodes (OLEDs) were prepared, which employ PCAN as an emitter. The vacuum deposited, non-doped EL device exhibited not only the excellent luminance efficiency and external quantum efficiency (as high as 3.64 cd A-1 and 4.61%, respectively) for the saturated deep-blue CIE chromaticity coordinates of (0.151, 0.086), but also stable performance and a good device lifetime. Furthermore, the solution processed EL device also exhibited an encouraging level of performance (1.24%, 1.15 cd A-1) and deep-blue emission (0.159, 0.105).

High performance deep-blue organic light-emitting diodes (OLEDs) have been investigated using new multifunctional blue emitting materials 3-(anthracen-9-yl)-9-ethyl-9H-carbazole (AC), 3,6-di(anthracen-9-yl)-9-ethyl-9H- carbazole (DAC), 3-(anthracen-9-yl-)-9-phenyl-9H-carbazole (P-AC), and 3,6-di(anthracen-9-yl)-9-phenyl-9H-carbazole (P-DAC) which comprise covalently bonded carbazole and anthracene moieties. We also have investigated the thermal, electrochemical, and morphological stability to find suitable molecular structure, consisting of carbazole and anthracene moieties. The non-doping deep-blue OLEDs using P-DAC, which showed the highest thermal, electrochemical, and morphological stability, proved the highest luminance efficiency and external quantum efficiency of 3.14 cd A-1 and 2.75%, with the Commission Internationale de l'Eclairage (CIE) chromaticity coordinates (0.162, 0.136) at 100 mA cm-2. Moreover, the doping devices using P-DAC as the host material showed blue emission, and the high luminance efficiencies and external quantum efficiencies of as high as 7.70 cd A-1 and 4.86% with CIE chromaticity coordinates (0.156, 0.136) and (0.156, 0.217) at 100 mA cm-2. Both the non-doping and doping devices using P-DAC uniquely exhibited high operational stability with virtually negligible efficiency roll-off over the broad current density range.

BICARBAZOLE CONTAINING COMPOUNDS FOR OLEDS
Novel organic compounds comprising a bicarbazole core are provided. In particular, the compound has a 3; 31 -bicarbazole core substituted at the 9 th position with at least one of dibenzofuran, dibenzothiophene, dibenzoselenophene, azadibenzofuran, azadibenzothiophene and azadibenzoselenophene. The compounds may be used in organic light emitting devices ( 100, 200 ) to provide devices having improved efficiency and improved lifetime.
