Abstract: Time-resolved fluorescence spectra were applied to study the binding of dansyl-L-serine(DLS) with β-cyclodextrin(β-CD), 2-selenium bridged β-cyclodextrin(1) and 2-tellurium bridged β-cyclodextrin(2). The differentiations of DLS in binding with three kinds of cyclodextrins were performed. The results suggest that compound 1 cannot bind with DLS efficiently. However, compound 2 can enhance the binding ability with DLS greatly in comparison with that of β-CD.

Key words: Dansyl-L-serine, 2-Selenium bridged β-cyclodextrin, 2-Tellurium bridged β-cyclodextrin, Non-linear least-square curve fitting, Time-resolved fluorescence spectroscopy
