Electron transfer dynamics in dye sensitized solar cells (DSSCs) employing triphenylamine Y123 were investigated by means of femtosecond broadband transient absorption spectroscopy the visible and mid-IR range detection. The electron injection process to titania conduction band was found appear biphasically with time constant first component within 350 fs that second between 80 95 ps. Subsequen...
A functional ruthenium(ii) complex, [Ru(bpy)2(AN-bpy)](PF6)2 (bpy: 2,2'-bipyridine, AN-bpy: 4-methyl-4'-(4-amino-3-nitro-phenoxy-methylene)-2,2'-bipyridine), has been designed and synthesized as a turn-on luminescent probe for the imaging of hypochlorous acid (HOCl) in living cells. Due to the intramolecular photoinduced electron transfer (PET), the ruthenium(ii) complex itself is almost non-lu...
The highly unfavorable thermodynamics of direct aluminum hydrogenation can be overcome by stabilizing alane within a nanoporous bipyridine-functionalized covalent triazine framework (AlH3@CTF-bipyridine). This material and the counterpart AlH3@CTF-biphenyl rapidly desorb H2 between 95 154 °C, with desorption complete at 250 °C. Sieverts measurements, 27Al MAS NMR 27Al{1H} REDOR experiments, com...
The title compound, (C(10)H(9)N(2))[Cr(C(7)H(3)NO(4))(2)]·4H(2)O or (4,4'-bipyH)[Cr(pydc)(2)]·4H(2)O (where 4,4'-bipy is 4,4'-bipyridine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of chromium(III) chloride hexa-hydrate with pyridine-2,6-dicarboxylic acid and 4,4'-bipyridine in a 1:2:4 molar ratio in aqueous solution. This compound is composed of an anionic ...
A series of stable platinum complexes containing closo-carborane cages in a 'carrier group', which could be potentially utilized for boron neutron capture therapy (BNCT), was successfully synthesized and characterized by various spectroscopic methods. Two ortho-closo-carborane cages were connected to the 3,3' or 4,4'-positions of 2,2'-bipyridine through ester bonds to give three carborane-linke...
Two novel heteroleptic sensitizers, Ru((4,4-dicarboxylic acid-2,2'-bipyridine)(4,4'-bis(p-hexyloxystyryl)-2,2-bipyridine)(NCS)2 and Ru((4,4-dicarboxylic acid-2,2'-bipyridine)(4,4'-bis(p-methoxystyryl)-2,2'-bipyridine) (NCS)2, coded as K-19 and K-73, respectively, have been synthesized and characterized by 1H NMR, FTIR, UV-vis absorption, and emission spectroscopy and excited-state lifetime and ...
For the spin crossover coordination polymer [Fe(L1)(bipy)]n (where L1 is a N2O22− coordinating Schiff base-like ligand bearing phenazine fluorophore and bipy = 4,4′-bipyridine), there compelling additional evidence of state transition.
Four new 2,2'-bipyridine and 1,10-phenanthroline complexes, namely [Mn(phenca)(2)]·(H(2)O)(2) (1), [Cu(4)(phen)(4)(OH-)(4)(H(2)O)(2)](DMF)(4)(ClO(4)-)(4)(H(2)O) (2), [Cu(2)(2,2-bipy)(2)(C(2)O(4)2-)(H(2)O)(2)(NO(3))(2)] (3) and [Cu(2,2-bipy)(2)(ClO(4)-)](ClO(4)-) (4) (2,2'-bpy = 2,2'-bipyridine, Hphenca = 1,10-phenanthroline-2-carboxylic acid) have been synthesized by a hydrothermal reaction. Th...
Two heteroleptic nickel oxothiolate complexes, namely [Ni(bpy)(mp)] (1) and [Ni(dmbpy)(mp)] (2), where mp = 2-hydroxythiophenol, bpy 2,2?-bipyridine dmbpy 4,4?-dimethyl-2,2?-bipyridine were synthesized characterized with various physical spectroscopic methods. Complex 2 was further by single crystal X-ray diffraction data. The complex crystallizes in the monoclinic P 21/c system its neutral for...
