実験手順

19.6 g (110 mmol) of N-bromosuccinimide are added in one portion at 100° C. with vigorous stirring to a suspension of 22.7 g (50 mmol) of 4-(benz[a]anthracen-4-yl)benz[a]anthracene in 1000 ml of DMF. The suspension is kept at 100° C. for a further 30 min. and cooled, and 1000 ml of ethanol are then added. The precipitated solid is filtered off with suction, washed three times with 100 ml of ethanol each time and dried in vacuo. The resultant solid is reacted analogously to Example 7 with 15.9 g (130 mmol) of benzeneboronic acid, Recrystallisation five times from DMF (about 6 ml/g); sublimation (p=5×10−5 mbar, T=360° C.). Yield: 21.8 g (36 mmol), 72.0%, purity 99.9% (HPLC), Tg=181.4° C.
