英文摘要Steady-state absorption and fluorescence, circular dichroism and picosecond time-resolved fluorescence spectroscopies were used to investigate the interaction between 5, 10, 15, 20-tetrakis ( 4-N-methylpyridine)porphyrin (TMPyP4) and nucleic acid molecules, i. e. bases (A, G, T, C), deoxynucleosides (dA, dG, dT, dC), deoxynucleotides (dAMP, dGMP, dTMP, dCMP) and oligonucleotides ( dA,, dG,, dT,, dC,). The results show that the interactions between TMPyP4 and the purine species were stronger than that between TMPyP4 and the pyrimidine species. For a certain series of species, such as A, dA, dAMP and dA(6) the interaction strength follows the order: base-nucleoside < nucleotide < oligonucleotide. Except for the G series, the TMPyP4-nucleic acid complexes exhibit a fast ( 1-2 ns) and a slow( about 10 ns) decay component, reflecting the influence from the exciplex and that from the low dielectric constant of the TMPyP4 surroundings, respectively. Oligonucleotides are able to induce the circular dichroism of TMPyP4 in its Soret-band spectral region, whereas all of the monomeric nucleic acids cannot do so.
