Title: | Spectrophotometric study of fluorescence sensing and selective binding of biochemical substrates by 2,2'-bridged biso(β-cyclodextrin) and its water-soluble fullerene conjugate | Authors: | Liu, Yu Liang, Peng Chen, Yong Zhao, Yanli Ding, Fei Yu, Ao |
Keywords: | DRNTU::Science::Biological sciences::Biochemistry | Issue Date: | 2005 | Source: | Liu, Y., Liang, P., Chen, Y., Zhao, Y. L., Ding, F., & Yu, A. (2005). Spectrophotometric study of fluorescence sensing and selective binding of biochemical substrates by 2,2'-bridged biso(beta-cyclodextrin) and its water-soluble fullerene conjugate. Journal of Physical Chemistry B, 109(49), 23739-23744. | Series/Report no.: | Journal of physical Chemistry B | Abstract: | A bis(β-cyclodextrin)-fullerene conjugate (3) linked at the secondary hydroxyl side was prepared in a good yield from its precursor N,N'-bis(2-(2-aminoethylamino)ethyl)malonamide-bridged bis(β-cyclodextrin) (2). Spectrophotomeric studies on the conformation and the inclusion complexation behavior of 3 with a variety of organic and biochemical substrates by means of UV-vis, FT-IR, NMR, fluorescence, and circular dichroism spectroscopy showed that the bis(β-cyclodextrin)-fullerene conjugate displayed an intramolecular capsuletype conformation in aqueous solution. Because of the multiple binding of bis(β-cyclodextrin) with substrates, 2 can act as an efficient fluorescence sensor for biochemical substrates, while its fullerene conjugate 3 displays a capability of cleaving DNA under visible-light irradiation. | URI: | https://hdl.handle.net/10356/101875 http://hdl.handle.net/10220/6997 |
