| 摘 要： | 研究了在pH5.3的醋酸-醋酸钠缓冲体系中,四甘醇醛缩苯丙氨酸Schiff碱与铜的双核配合物(Cu2L(NO3)]NO3)与DNA作用的情况.结果表明Cu2L(NO3)]NO3在此体系下具有较强的荧光,DNA加入后对其荧光有一定的敏化作用.探讨了造成此种现象的可能原因,并推导了该二元体系的结合常数.

| Abstract: | Cu2L(NO3)]NO3(L:noncyclic polyether-phenylalanine schiff base) was studied with respect to its binding to calf thymus DNA by absorption and fluorescence spectra.Cu2L(NO3)]NO3 has strong fluorescence intensity.The addition of DNA enhances the intensity in pH5.3 NaAc-HAc buffer.The complex formation constants were determined. |
