Abstract:

A series of aromatic oligosulfonate-bridged macrocyclic compounds was synthesized using aromatic disulfonyl chlorides and aromatic diphenol as the starting materials. The products were characterized by IR, 1H NMR,13C NMR and MALDI-TOF-MS. The synthetic methods, UV spectra and variable-temperature 1H NMR experiments were also discussed herein. UV spectra maximum absorption peaks of compounds 3~5 and compound 6 in DMF solutions are at 266 nm and 267 nm, respectively. The molar absorption coefficients are 4.65×104, 5.61×104, 5.09×104 and 9.98×104 L/(mol·cm), respectively. The detection limits are 2.15×10-7, 1.78×10-7, 1.96×10-7 and 1.00×10-7 mol/L, respectively. Variable-temperature 1H NMR experiments show that branched benzene rings can lock the conformation and facilitate the synthesis of desired macrocylces.
