要旨

The kinetics of the electron transfer reactions between pentaammine(pyrazine)ruthenium(II), [Ru(NH3)5pz]2+ and tris(oxalate)cobalt(III), [Co(C2O4)3]3− and pentaammine(pyridine)ruthenium(II), [Ru(NH3)5py]2+ and tetraammine(pyrazinecarboxylate)cobalt(III), [Co(NH3)4pzCO2]2+ have been studied in aqueous solutions of DNA over the concentration ranges 0 to 2.46 × 10−3 mol dm−3 and 1.23 × 10−4 to 1.00 × 10−3 mol dm−3, respectively. The results are interpreted on the basis of a modified pseudophase model which takes into account the anticooperative character of the binding of the cationic reactants to DNA.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
