Fe(II) coordination polymers: Structures and surface photoelectric properties

Raman Studies of Bis(phenylterpyrazine)iron(ii) and Supramolecular Species With Pentacyanidoferrate(ii) Ions

“…Iron(II) terpyridine complexes are classical examples of coordination compounds exhibiting a typical (terimine)iron(II) chromophore in a low spin configuration. [1][2][3] The complexes have been extensively employed in analytical chemistry, coordination polymers 4 and devices 5 because of their strong red-violet colors associated with metal-to-ligand charge-transfer transitions in the visible region. However, the analogous iron(II) terpyrazine complexes remain poorly understood, and according to the best of our knowledge, they have never been investigated before from the point of view of their electronic, Raman and supramolecular properties in aqueous solution.…”

Two novel oxovanadium–organophosphonate hybrids with a 3D supramolecular structure: synthesis, crystal structures, surface photovoltage and luminescent properties

“…As far as band to band transitions are concerned, a positive response of surface photovoltage (SPV) (dVs > 0) indicates that the sample is characterized as a p-type semiconductor, whereas a negative response corresponds to an n-type semiconductor. 20 The magnitude of the surface potential barrier depends on the net surface charge.
