1.	Johansson, O., et al. (author) Intramolecular charge separation in a hydrogen bonded tyrosine-ruthenium(II)-naphthalene diimide triad 2004 In: Chemical Communications. - : Royal Society of Chemistry (RSC). - 1359-7345 .- 1364-548X. ; :2, s. 194-195, s. 194-195 Journal article (peer-reviewed)abstract Long-lived charge-separated states in the ns to mus range were observed upon laser flash excitation of a donor-chromophore-acceptor triad based on tris(bipyridine) ruthenium(II) as photosensitizer, naphthalene diimide as acceptor; and a hydrogen bonded phenol as donor.
2.	Wolpher, H., et al. (author) A tridentate ligand for preparation of bisterpyridine-like ruthenium(II) complexes with an increased excited state lifetime 2004 In: Inorganic Chemistry Communications. - : Elsevier BV. - 1387-7003 .- 1879-0259. ; 7:3, s. 337-340 Journal article (peer-reviewed)abstract A new tridentate polypyridine ligand, 6-(2-picolyl)-2,2'-bipyridine, as well as its homoleptic Ru(II) complex has been prepared. Photophysical studies show a prolonged lifetime of the excited state compared to [Ru(tpy)2](2+), where tpy is 2,2':6',2-terpyridine.
3.	Wolpher, H., et al. (author) Synthesis and properties of an iron hydrogenase active site model linked to a ruthenium tris-bipyridine photosensitizer 2003 In: Inorganic Chemistry Communications. - 1387-7003 .- 1879-0259. ; 6:8, s. 989-991 Journal article (peer-reviewed)abstract A dinuclear iron complex, related to the active site of Fe hydrogenases, has been covalently linked to a redox active ruthenium tris-bipyridine type photosensitizer. Photophysics and electrochemistry of this system are studied in solution. IR spectra of this complex together with its precursor, the dinuclear iron complex, were also shown.
4.	Wolpher, H., et al. (author) Synthesis of a Ru(bpy)(3)-type complex linked to a free terpyridine ligand and its use for preparation of polynuclear bimetallic complexes 2004 In: Catalysis Today. - : Elsevier BV. - 0920-5861 .- 1873-4308. ; 98:4, s. 529-536:98, s. 529-536 Journal article (peer-reviewed)abstract A terpyridine ligand has been covalently linked to a Ru(bpy)(3) complex via an amide bond. By using this functionalized terpyridine ligand, a series of multinuclear bimetallic complexes have been synthesized and characterized. One of these complexes has the structure of di-mu-oxobridged Mn dimer. EPR spectra of this complex showed that, depending on the procedure for the preparation, the oxidation states of the Mn dimer is either a Mn-2(III,IV) dimer or a mixture of this and Mn-2(IV,IV) dimer. Water oxidation catalyzed by this complex has been performed.
