摘要

The photophysical and photochemical behavior of a series of hairpin-forming DNA conjugates possessing a 5′-tethered pyrenecarboxamide chromophore and one or two bromouracil bases has been investigated. Quenching of the pyrene fluorescence and transient absorption spectra characteristic of the pyrene cation radical are observed only when bromouracil is located at the first or second base pair position nearest to the point of ...
