AIE (aggregation-induced emission)-active building block. | [Synthesis]
[0085] 1) Synthesis of 1,1,2,2-tetrakis(4-bromophenyl)ethylene (A). 75 mmol (25 g) of 1,1,2,2-tetraphenylethylene was placed on a watch glass in a desiccator. Add 585 mmol (30 mL) of liquid bromine to the bottom of the desiccator. The desiccator was closed with a lid with small holes to allow the HBr gas generated by the reaction to escape.After 7 days, the resulting yellow solid was collected and recrystallized with dichloromethane/methanol (2:1, v/v) to give a white crystalline product. Yield: 37 g, 76% yield.1H NMR (CDCl3, 300 MHz, 298 K): δ 6.84 (d, 8H, HarH), 7.26 (d, 8H, HbrH). Impurity peak: δ 7.26 (m, CDCl3), δ 1.6 (m, H2O). | [References]
