실험 절차

Clear solutions of 2,6-pyridinedicarbonyl dichloride (84 mg, 0.41 mmol) in 15 mL of chloroform and 9,10-bis(aminomethyl)anthracene (97 mg, 0.41 mmol) in 15 mL of chloroform were simultaneously added dropwise over 10 h to a stirred solution of squaraine 13a (32 mg, 0.05 mmol, synthesized according to E. Arunkumar et al. Chem. Eur. J. 2006, 12, 4884-4690) and triethylamine (81 mg, 0.8 mmol) in 30 mL of chloroform. After overnight stirring, the mixture containing rotaxane 13 and polymer co-products was filtered, washed with chloroform (100 mL) to extract rotaxane 13, and the filtrate was concentrated. Purification of the crude material by column chromatography using silica gel (gradient, 0-1% of MeOH in CHCl3) gave the rotaxane 13. λmax (abs): 651 m, λmax (em): 707 nm, 59% (methanol); λmax (abs): 648 nm, λmax (em): 700 nm, Q.Y.: 65% (chloroform).
