1,3-Bis(4-hydroxyphenyl)adamantane (1,3-BPA) was synthesized as an aromatic diol monomer. First, 1,3-dibromoadamantane (1.876 g, 6.38 mmol) and phenol (28.1 mL, 0.32 mol) was added to a 50 mL 3-bulb flask, slowly heated to 185° C. under nitrogen atmosphere and stirred for 5 hours. After dissolving in 10 mL methanol, followed by precipitating in water (200 mL) at 60° C., the precipitate was filtered from the hot solution and then purified with MC and water. Thus obtained 1,3-BPA was recrystallized with MC to obtain pure 1,3-BPA (yield: 75%) of the following structure. Melting temperature was 200° C.
