Multinuclear Metal Nucleobase Complexes
Of all properties of metal nucleobase complexes, formation of multinuclear species appears to be an outstanding feature. After a brief introduction into well known polymeric metal nucleobase complexes, three aspects recently Studied in our laboratory will be dealt with in more detail: (i) Heteronuclear complexes derived from trans-[(amine)(2)Pt(1-MeC)(2)](2+) (1-MeC=1-methylcytosine). They form...
متن کاملElectronic and Structural Elements That Regulate the Excited-State Dynamics in Purine Nucleobase Derivatives
The excited-state dynamics of the purine free base and 9-methylpurine are investigated using experimental and theoretical methods. Femtosecond broadband transient absorption experiments reveal that excitation of these purine derivatives in aqueous solution at 266 nm results primarily in ultrafast conversion of the S2(ππ*) state to the vibrationally excited (1)nπ* state. Following vibrational an...
متن کاملCanonical and unconventional pairing schemes between bis(nucleobase) complexes of trans-a2PtII: artificial nucleobase quartets and C-H...N bonds.
If two nucleobases are crosslinked by trans-a(2)Pt(II), self-association via H bonding may take place either through individual bases or jointly through both bases. Due to the blockage of an acceptor site by the metal, the number of feasible pairing patterns can be reduced, and the preferred ones altered. If the metalated base pair as a whole undergoes association, base quartets can form. Vario...

متن کاملGround state structures and photoelectron spectroscopy of [Com(coronene)]- complexes.
A synergistic approach involving theory and experiment has been used to study the structure and properties of neutral and negatively charged cobalt-coronene [Com(coronene)] complexes. The calculations are based on density functional theory with generalized gradient approximation for exchange and correlation potential, while the experiments are carried out using photoelectron spectroscopy of mas...
