Procedure

2.0 g of 4,4′-dibromo-2,2′-diiodo-5,5′-dioctyloxy-1,1′-biphenyl synthesized as above was put in a 100 ml flask in an atmosphere of nitrogen and 20 ml of tetrahydrofuran was added to dissolve the same. Then, the tetrahydrofuran solution was cooled to −90° C. and 3.4 ml of 1.6M hexane solution was added dropwise. After 1-hour stirring, a solution of 1.5 g of magnesium bromide in 20 ml of tetrahydrofuran was added, warmed to room temperature, and stirred for 1 hour. The mixture was cooled again to −90° C., and 1.01 g of (2,4,6-triisopropylphenyl)dimethoxyborane was added. After warming, the mixture was allowed to react under reflux for 12 hours.
