SPB was prepared according to the synthesis scheme shown in FIG. 2. In 20 ml of dimethylsulfoxide (DMF), 2.25 g of 1-pyrenebutanoic acid (7.8 mmol: obtained from Molecular Probes, Inc.) and 1.2 g of N-hydroxy succinimide (10.4 mmol: obtained from Wako Pure Chemical Industries, Ltd.) were dissolved. After the mixed solution was cooled to 0° C., 2.69 g of 1,3-dichlorohexylcarbodiimide (13.1 mmol: DCC) was added thereto. Then, the mixture was reacted at 0° C. for 24 hours while stirring. After the reacted solution was filtered with a 0.45 μm filter, the filtrate was collected and dried using an evaporator. Then, the filtrate was recrystallized from 95% ethanol, thereby obtaining 1.88 g of succinimidyl-1-pyrenebutanoic acid (yield: 70%).
