The deconvolution analysis of the Eu[2,3-Nc(SC (sub)12 H (sub)25) (sub)8] (sub)2 spectra is presented. Results indicate spectral changes in the oxidation and reduction of the complexes.

Time-resolved electron pragmatic resonance (TREPR) study on three oxidation states of Lu(TAP)2, where the lowest excited states of oxidized and reduced forms are quantitatively characterized is described. This kind of TREPR application will provide the novel information on antiferromagnetic interactions between paramagnetic species.

Discusses the synthesis of structurally modified, alkylthio-substituted phthalocyanines by cyclic tetramerization of napthalonitriles. Deconvolution analysis of the spectra of the compound; Elucidation of the effects of ring substituents on transition energies; Chemical oxidation and reduction of the complexes.

Several cofacial phthalocyanines (Pcs) with an Si-Si linkage were obtained by one-step condensation of 1H-isoindole-1,3(2H)-diimine with hexachlorodisilane as template in quinoline. They were characterized by gel-permeation chromatography, IR, NMR spectroscopy, and mass spectrometry, and cyclic voltammetry. The results strongly suggest that we indeed obtained Pc dimers directly linked by an Si-Si bond using this novel concept of utilizing a compound/salt with an element-element bond as a template. The cofacial dimer structures are reasonably supported by X-ray absorption near-edge structure (XANES), electronic absorption and magnetic circular dichroism (MCD) spectra, and molecular orbital (MO) calculations. Interestingly, they show an electronic absorption spectrum very similar to that of silicon tetrabenztriazacorrole (SiTBC).
