Unprecedented [mu]4-[C2.sup.6-] anion in Sc4C2 at the rate of C80

Article Abstract:

The density functional calculations are used to show that an unprecedented [mu]4-[C2.sup.6-] anion can viably exist as an endohedral [[Sc4C2].sup.6+] cluster in the endofullerene Sc4C2 at the rate of C80. The predicted Sc4C2 at the rate of C80 structure has a stable closed-shell electronic configuration and has a five-membered endohedral cluster.

Time-dependent binding mode of a cationic porphyrin dimer to poly[d[(G-C).sub.2]] and poly[d[(A-T).sub.2]]

Article Abstract:

The spectroscopic studies of the time-dependent binding mode of a porphyrin dimer to poly[d[(G-C).sub.2]] and poly[d[(A-T).sub.2]) is described. The changes observed in the spectral properties are attributed to the conformational change of poly[d[(A-T).sub.2]] near the binding site.
