抄録

Resonance energy transfer between two cationic porphyrins, viz., (<I>meso</I>-tetrakis(<I>N</I>-methylpyridinium-4-yl)porphyrin and its zinc derivative, along a model DNA, poly(dA-dT) as a template is demonstrated. The rate of energy transfer (<I>k</I><SUB>EnT</SUB>), quantum yield (Φ<SUB>EnT</SUB>), and critical transfer distance are evaluated to be 1.78×10<SUP>9</SUP> s<SUP>−1</SUP>, 0.74, and 23 Å, respectively, indicating efficient energy transfer process.
