Abstract:
Teraaza- and hexaazacyclophanes have been synthesized via a one-step palladium catalyzed amination reaction. The chemical oxidation of cyclophanes leads to the formation of radical cations, the presence of which was manifested by the appearance of new bands in UV-Vis-NIR and IR spectra. Spins of radical cations can be magnetically coupled. The nutation pulsed-EPR technique (PEANUT experiment) enables us to determine the multiplicity of the systems for different oxidant/cyclophane ratios. Spins of cyclophanes oxidized to diradical dications interact ferromagnetically to form a pure triplet state.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
