[0038] (1) Synthesis of monomer M1

[0039]

[0040] 4,4'-Dibromo-2-nitro-1,1'-biphenyl (1)

[0041] Dissolve 4,4'-dibromo-1,1'-biphenyl (10.00g, 32.00mmol) in acetic acid (300ml), slowly add HNO at 100°C 3 Mixture with water (7.5ml). After heating at 100°C for 30 minutes, the initially formed precipitate dissolved. After the reaction, the solution was cooled, and a yellow powder was obtained after filtration. Recrystallization in ethanol gave the title product (9.30 g, 81%). 1 H NMR (400MHz, CDCl 3 ): δ8.03(d, J=1.3Hz, 1H), 7.75(m, 1H), 7.56(d, J=7.9Hz, 2H), 7.28(m, 1H), 7.16(d, J=7.9Hz , 2H).
