Electric Literature of C9H7ClF3NOOn March 10, 2015, Gantenbein, Markus; Hellstern, Manuel; Le Pleux, Loic; Neuburger, Markus; Mayor, Marcel published an article in Chemistry of Materials. The article was 《New 4,4′-Bis(9-carbazolyl)-Biphenyl Derivatives with Locked Carbazole-Biphenyl Junctions: High-Triplet State Energy Materials》. The article mentions the following:
We synthesized a series of 4,4′-bis(9-carbazolyl)-biphenyl (CBP) derivatives, using Me groups as spatially demanding groups, locking the angle between the carbazole subunit and the biphenyl backbone as potential matrix material for blue organic light-emitting diodes (OLEDs). The locked rotation was achieved by four Me groups either in positions 1 and 8 of the carbazole subunit (1) or in positions 3, 5, 3′, and 5′ of the biphenyl subunit (2), and the fixed spatial arrangement was confirmed by X-ray anal. The phys. properties of CBP derivatives based on parent structure 2 were further tailored by electron-withdrawing CF3 groups in positions 3 and 6 (3) or positions 2 and 7 of the carbazole subunits (4) or alternatively by electron-donating CH3O groups in positions 2 and 7 (5) of the same building blocks. Increased triplet energies (ET) compared to that of the parent compound CBP were found for all synthesized CBP derivatives 1-5. Enhanced glass transition temperatures ranging between 129 and 202 °C further corroborate the application potential of these derivatives for matrix material in blue OLEDs. In the experiment, the researchers used N-(2-Chloro-4-(trifluoromethyl)phenyl)acetamide(cas: 247170-19-0Electric Literature of C9H7ClF3NO)
N-(2-Chloro-4-(trifluoromethyl)phenyl)acetamide(cas: 247170-19-0) belongs to anime. Examples of direct uses of amines and their salts are as corrosion inhibitors in boilers and in lubricating oils (morpholine), as antioxidants for rubber and roofing asphalt (diarylamines), as stabilizers for cellulose nitrate explosives (diphenylamine), as protectants against damage from gamma radiation (diarylamines), as developers in photography (aromatic diamines), as flotation agents in mining, as anticling and waterproofing agents for textiles, as fabric softeners, in paper coating, and for solubilizing herbicides.Electric Literature of C9H7ClF3NO
