실험 절차

A suspension of [1,1′;4′,1″]terphenyl-4,4″-dicarboxylic acid (6.37 g, 20 mmol) in 100 ml of thionyl chloride was heated at reflux for 12 h then thionyl chloride was evaporated by azeotropic distillation. The crude yellow residue obtained therefrom was mixed with 10-undecen-1-ol (7.49 g, 44 mmol) in dichloromethane (300 ml) and triethylamine (8.9 g, 88 mmol) was added dropwise to the resulting mixture. The reaction mixture was stirred at 6 h at room temperature, then poured into water (300 ml) and extracted with dichloromethane (2×400 ml). The combined organic extracts were washed with saturated NaCl solution (500 ml), dried over magnesium sulphate, filtered and evaporated to dryness to give a brownish residue which was recrystallised from acetone/dichlorometane: 9/1 to afford pure [1,1′;4′,1″]terphenyl-4,4″-dicarboxylic acid diundec-10-enyl ester as white crystalline material. Yield 8.97 g.
