## Abstract The macrocyclic porphyrin 5,10,15,20‐tetrakis(1‐methyl‐4‐pyridiyl)‐porphine is studied in its ability to coordinate Cu(II) even at very low pH values and to interact, as a copper complex, with calf‐thymus (CT‐DNA). The kinetics and equilibria for metal‐ligand complexes formation are spe
Interaction between molecular oxygen and the cationic fiee-base 5,10,15,20-tetrakis(4-N-methylpyridyl )porphyrin (H2TMpyP 4, ) complexed with [poly(dA-dT)I\_+, l poly(dG-dC) ]z and calf thymus DNA, has been monitored in air-saturated heavy water solutions through porphyrin triplet-triplet absorption
