실험 절차
A 10.0 g quantity of 9-fluorenone-4-carbonyl chloride (0.04 mole, obtained from Aldrich Chemicals Co, Milwaukee, Wis. 53201, USA) and 100 ml of tetrahydrofuran (obtained from Aldrich) were added to a 250 ml, 3-neck round bottom flask equipped with a reflux condenser and a mechanical stirrer. The solution was stirred for about ½ hour, and then 5.16 g of 4,4′-thiobisbenzenethiol (0.02 mole, obtained from Aldrich) in 50 ml of tetrahydrofuran were added, followed by the addition of 4.17 g of triethylamine (0.04 mole, obtained from Aldrich). The solution was refluxed for 6 hours, filtered hot to remove triethylamine hydrochloride salt byproduct and the filtrate was evaporated to dryness to obtain a first dimeric fluorenone derivative. The first dimeric fluorenone derivative was recrystallized from tetrahydrofuran/methanol with activated charcoal. The first dimeric fluorenone derivative was dried at 60° C. vacuum oven for 6 hours to yield a yellow solid (6.85 g, 50% yield).
