| | 3,3′-Di(9H-carbazol-9-yl)biphenyl Usage And Synthesis |
| Description | mCBP, 3,3′-Di(9H-carbazol-9-yl)-1,1′-biphenyl, is an isomer of CBP, 4,4′-Di(9H-carbazol-9-yl)-1,1′-biphenyl. The meta-linkage in mCBP limits conjugation to the central biphenyl, preventing excimer formation and thus resulting in a higher triplet energy of 2.8eV. | | General Description | Phosphorescent host material and TADF emitter in OLEDs. | | Synthesis | General procedure for the synthesis of 3,3'-bis(9H-carbazol-9-yl)-1,1'-biphenyl, compounds (CAS:1325751-60-7) and 4,4'-bis(9-carbazolyl)biphenyl from 4,4'-dichlorobiphenyl and carbazole: Potassium tert-butoxide (1.12 g, 10 mmol) and carbazole (1.67 g, 10 mmol) were added to an anhydrous toluene containing 1 mmol of appropriate dihalogenated biphenyl in a solution of anhydrous toluene (20 mL). The mixture was placed in a glass autoclave under argon protection and heated at 130-140 °C for 48 hours. Upon completion of the reaction, the resulting suspension was diluted with water to remove inorganic impurities. The organic layer was separated, concentrated to dryness and purified by silica gel column chromatography using a hexane solution of 0-10% acetone as eluent. 4,4'-Bis(9H-carbazol-9-yl)-1,1'-biphenyl (2a) was obtained in a yield of 0.43 g (90% yield) with a melting point of >250 °C. Elemental analysis measured values (%): C, 89.08; H, 4.84. theoretically calculated values (%) for C36H24N2: C, 89.23; H, 4.99. 1H NMR (DMSO-d6, δ): 8.28 (m, 4H); 8.09 (m, 4H); 7.80 (m, 4H); 7.47-7.50 (m, 8H); 7.26- 7.28 (m, 4H). esims, m/z (% relative strength): 485.20 [M+H]+ (100). | | References | [1] Russian Chemical Bulletin, 2015, vol. 64, # 8, p. 1978 - 1981
