実験手順

A solution of 3,5-bis{3′,5′-bis[3″,5″-bis(3′″,5′″-di-tert-butylstyryl)styryl]styryl}benzaldehyde (3.853 g, 1.585 mmol) in tetrahydrofuran (50 cm3) was treated with sodium borohydride (121 mg, 3.20 mmol) and heated at reflux for 135 min. The solvent was removed. Dichloromethane (50 cm3) was added and the solution washed with water (50 cm3) and brine (50 cm3), dried over sodium sulphate, filtered and the solvent removed to leave a yellow foam. The product was purified by column chromatography over silica, eluting with dichloromethane-light petroleum (2:3). Recrystallisation from a dichloromethane-methanol mixture gave 3,5-bis{3′,5′-bis[3″,5″-bis(3′″,5′″-di-tert-butylstyryl)styryl]styryl}benzyl alcohol (3.07 g, 80%) as a yellow powder, mp 248° C.
