반응 단계

Preparation analogous to Example 7. The 19.2 g (50 mmol) of 9-bromo-10-(2-naphthyl)anthracene are replaced by 15.4 g (50 mmol) of 5-bromobenz[a]anthracene, and the benz[a]anthracene-4-boronic acid is replaced by benz[a]anthracene-5-boronic acid. Recrystallisation four times from o-dichlorobenzene (about 15 ml/g); sublimation (p=5×10−5 mbar, T=320° C.). Yield: 15.0 g (33 mmol), 66.0%, purity 99.9% (HPLC), Tg=141.2° C.
