Reaction Steps
Preparation analogous to Example 7. 9-Bromo-10-(2-naphthyl)anthracene is replaced by 15.4 g (50 mmol) of 4-bromobenz[a]anthracene. Recrystallisation four times from o-dichlorobenzene (about 15 ml/g); sublimation (p=5×10−5 mbar, T=320° C.). Yield: 16.8 g (37 mmol), 74.0%, purity 99.9% (HPLC), Tg=130.3° C.
