Lifting the diiron curtain: 200 equivalents of H2 per catalyst at a maximum turnover rate 3.7 minute can be obtained in light-driven proton reduction process near-neutral H2O/DMF (pH 5.5) by using an [FeFe]-hydrogenase active-site model complex as (see scheme). Detailed facts importance to specialist readers are published "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted authors.

Flicking a switch: Photoinduced electron transfer (PET) occurs between the perylene and closed (but not open) form of diarylethene unit in prototype optical memory system based on photochromic diarylethene-perylene bisimide dyad (see picture). This allows three different wavelengths to be used for read, write, erase steps without destructive readout occurring by cycloreversion. Supporting information this article is available WWW under...
The tetraruthenium polyoxometalate water oxidation catalyst 1 performs very fast hole scavenging from photogenerated Ru(iii) polypyridine complexes, both in homogeneous solution and at a sensitized nanocrystalline TiO(2) surface.
The relationship between the unique characteristics of nanodiamonds (NDs) and fluorescence properties nitrogen-vacancy (NV) centers has lead to a tool with quantum sensing capabilities nanometric spatial resolution; this is able operate in wide range temperatures pressures harsh chemical conditions. For development devices based on NDs, great effort been invested researching cheap easily scalable synthesis techniques for NDs NV-NDs. In review, we discuss common fluorescent as well...
The tetraruthenium polyoxometalate [Ru4(μ-O)4(μ-OH)2(H2O)4(γ-SiW10O36)2]10- (1) behaves as a very efficient water oxidation catalyst in photocatalytic cycles using Ru(bpy)32+ sensitizer and persulfate sacrificial oxidant. Two interrelated issues relevant to this behavior have been examined detail: (i) the effects of ion pairing between polyanionic cationic sensitizer, (ii) kinetics hole transfer from oxidized catalyst. Complementary charge interactions aqueous solution leads an static...
A very efficient and successful metal-mediated strategy towards the formation of a non-symmetric triad is described: appropriate Lewis acid and/or base functions on molecular components (a naphthalenediimide, an aluminium(III) porphyrin, ruthenium(II) porphyrin) lead to desired product uniquely. The photophysics was investigated in detail using time-resolved spectroscopy pico- nanosecond time domains. great potential interest as, while confining synthetic effort single components, it can...
Den Hebel umgelegt: Ein photoinduzierter Elektronentransfer (PET) zwischen der Perylengruppe und geschlossenen, nicht aber offenen Form Diaryletheneinheit charakterisiert den Prototyp eines optischen Speichers auf Grundlage einer photochromen Diarylethen-Perylenbisimid-Diade (siehe Bild). Für Lesen, Schreiben Löschen können drei unterschiedliche Wellenlängen verwendet werden, ohne dass es beim Auslesen zu unerwünschten Cycloreversion kommt.

Four porphyrin-Re(I) conjugates, in which a pyridylporphyrin chromophore is directly coordinated to the electron-acceptor fragment [ fac-Re(CO) 3(bipy)] (+), were prepared: dimeric and pentameric compounds 3(bipy)(4'MPyP)](CF 3SO 3) ( 1) (4'MPyP = 4'-monopyridylporphyrin) fac-{Re(CO) 3(bipy)} 4(mu-4'TPyP)](CF 4 2) (4'TPyP 4'-tetrapyridylporphyrin), corresponding with 3' rather than 4' porphyrins, 3(bipy)(3'MPyP)](CF 4(mu-3'TPyP)](CF 4). These adducts proved be very stable solution also...
Two sterically hindered zinc phthalocyanines bearing fluorous alkoxy substituents and carboxylic acid groups acting respectively as electron donor acceptor/anchoring units, were synthesized their ability to photosensitize nanocrystalline TiO2 films was investigated. The electronic properties of these new dyes characterized by combining UV−vis spectroscopy, electrochemical techniques DFT computation. Nanocrystalline electrodes treated with the assembled in dye-sensitized solar cells (DSCs)...
Abstract TiO 2 nanoparticles obtained by microwave-assisted hydrothermal synthesis were subjected to facile post-processing based on vacuum annealing. The resulting defective (TiO 2-x ) material showed extended light absorption in the visible range, enhancing sunlight compatibility. Structural and optical characterization point arising of an Urbach tail as main reason. was then employed photocatalyst for inactivation ciprofloxacin, emerging environmental threat source antimicrobial...
