Transient Absorption and RamanStudies on Exciplex FormationDynamics of PhotoexcitedCu(II)(TMpy‐P4) With SyntheticPolynucleotide

Exciplex formation dynamics of photoexcited copper(II) tetrakis (4‐ N ‐methylpyridyl) porphyrin (Cu(II)(TMpy‐P4)) with added poly(dA‐dT) 2 and poly(dG‐dC) 2 has been investigated by using femtosecond transient absorption and nanosecond and picosecond transient Raman spectroscopic methods.

Zusammenfassung:Exciplex formation dynamics of photoexcited copper(II) tetrakis (4‐ N ‐methylpyridyl) porphyrin (Cu(II)(TMpy‐P4)) with added poly(dA‐dT) 2 and poly(dG‐dC) 2 has been investigated by using femtosecond transient absorption and nanosecond and picosecond transient Raman spectroscopic methods. It was observed that the decay time constant of the exciplex is strongly dependent on the polynucleotide and has a strong correlation with the appearance of new transient Raman bands.
