supporting information, p. 6337 - 6341 (2021/08/23)
The nickel-catalyzed cross-electrophile coupling of aryl halides and alkyl halides enabled by ball-milling is herein described. Under a mechanochemical manifold, the reductive C-C bond formation was achieved in the absence of bulk solvent and air/moisture sensitive setups, in reaction times of 2 h. The mechanical action provided by ball milling permits the use of a range of zinc sources to turnover the nickel catalytic cycle, enabling the synthesis of 28 cross-electrophile coupled products.

Four new cross-conjugated small molecules based on a central benzo[1,2-d:4,5-d′]bisoxazole moiety possessing semi-independently tunable HOMO and LUMO levels were synthesized and the properties of these materials were evaluated experimentally and theoretically. The molecules were thermally stable with 5% weight loss occurring well above 350 °C. The cruciforms all exhibited blue emission in solution ranging from 433-450 nm. Host-guest OLEDs fabricated from various concentrations of these materials using the small molecule host 4,4′-bis(9-carbazolyl)-biphenyl (CBP) exhibited deep blue-emission with Commission Internationale de L'Eclairage (CIE) coordinates of (0.15 ≤ x ≤ 0.17, 0.05 ≤ y ≤ 0.11), and maximum luminance efficiencies as high as ~2 cd A-1. These results demonstrate the potential of benzobisoxazole cruciforms as emitters for developing high-performance deep blue OLEDs.

Paragraph 0076; 0077; 0078, (2016/10/09)
The invention relates to the technical field of organic semiconductor materials and especially relates to a soluble benzo compound, a preparation method and an application thereof. The compound is represented as the general formula (1) and belongs to a 3,5,6,10,12,13-hexasubstituted dibenzanthracene compound. In the compound, the dibenzanthracene having good planarity serves as a core, a plurality of substituted groups being introduced to the 3, 5, 6, 10, 12 and 13 positions. The compound is increased in solubility and meanwhile a compact [pi]-[pi] stack arrangement manner in the dibenzanthracene core is not damaged as far as possible, thereby achieving high field-effect mobility. The invention also provides the soluble benzo compound and an organic thin-film transistor using the same. The organic thin-film transistor is 0.34 cm/V*s in carrier mobility and reaches 10 in on/off current ratio.

(Chemical Equation Presented) The direct reductive cross-coupling of alkyl halides with aryl halides is described. The transformation is efficient (equimolar amounts of the starting materials are used), generally high-yielding (all but one between 55 and 88% yield), highly functional-group-tolerant [OH, NHBoc, NHCbz, Bpin, C(O)Me, CO2Et, and CN are all tolerated], and easy to perform (uses only benchtop-stable reagents, tolerates small amounts of water and oxygen, changes color when complete, and uses filtration workup). The reaction appears to avoid the formation of intermediate organomanganese species, and a synergistic effect was found when a mixture of two ligands was employed.
