[en] Ultrafast spectroscopy on a series of Fe(II) complexes finds an increase of the ³MLCT lifetime with increasing number of N-heterocyclic carbene (NHC) donor functions revealing a promising route for the design of Fe photosensitizers.

[en] High-spin ferrous metalloporphyrins Fe^II(NCH₃TPP)Cl, Fe^II(NCH₃TPP)Br, Fe^II(NCH₃TPP)ClO₄, and Fe^II(NCH₃OEP)Cl(NCH₃TPP-N-methyltetraphenylporphyrin, NCH₃OEP-N-methyloctaethylporphyrin) have been characterized by Moessbauer spectroscopy. Values of IS (0.8 mm/s versus α-Fe) typical for high-spin ferrous porphyrin and very large quadrupole splittings (≅4 mm/s) have been observed. Iron(II) N-methylporphyrins should be readily detected in proteins by means of Moessbauer spectroscopy. Such parameters are similar to those of symmetrical anionic five coordinate high-spin prophyrins [Fe^II(TPP)X]^-(X-halide). (orig.)

[en] The data obtained until now seem to indicate that the hydrogen production by hydrogenases induces a proton-hydride coupling. In taking the structures of theses enzymes active sites (determined by X-ray diffraction) as a basis, it can be thought that this proton-hydride coupling is facilitated by the juxtaposition of two protonation sites, the metallic center M and the basic group of an E ligand of the coordination sphere. Contrarily to the supposed running of the hydrogenases enzymes, the homogeneous catalysts of the protons reduction, described in the literature, present a reactivity which is either on an alone metallic site or on a metal-metal bond. This work deals then with the preparation of complexes having two juxtaposed protonation sites. Some iron dinuclear compounds have been synthesized and their properties studied. (O.M.)

[en] We have fabricated high-resolution microscale cross-patterns from two different Fe(II) spin crossover (SCO) complexes having transition temperatures ($T_{1/2}$) 259 K and 323 K, through lithographic techniques. We hope that our original approach will be useful to create futuristic multi-component SCO devices.
