Reaction Steps

Next, 50.2 g of the obtained 9,9-bis[4-(4-nitro-3-benzyloxyphenoxy)-phenyl]-2,7-di(1-adamantyl)-fluorene (46.8 mmol), 1.49 g of 10% palladium-activated carbon (1.40 mmol), 273 mL of N,N-dimethylformamide and a stirrer were charged in a 300 mL recovery flask and agitated at 25° C. for 24 hours under a hydrogen atmosphere. A reaction solution was filtered and then added to in 1 L of ion-exchange water. Solid precipitate was collected by filtration, then agitated in 1 L of ion-exchange water for another one hour and dried under reduced pressure, thus obtaining 34.6 g of 9,9-bis[4-(3-hydroxy-4-amino-phenoxy)-phenyl]-2,7-di(1-adamantyl)-fluorene (41.5 mmol; the yield was 88.7%).
