A new strategy to assemble multifunctional Anderson-type polyoxometalate platforms for the light-driven hydrogen evolution reaction (HER) is presented. The stepwise coordination of precursor metal complexes enables binding of an Ir photosensitizer or a Pt HER catalyst to the bipyridine coordination site.…

In this work, the synthesis and structural characterization of the smallest possible member of the family of bis -functionalized {MnMo 6 O 24 } Anderson–Evans polyoxometalates (POMs) is reported. The synthesis of the title compound TBA 3 {[HC(CH 2 O) 3 ] 2 MnMo 6 O 18 } ( 1 ) was accomplished by using…
Excited‐state proton transfer (ESPT) roots in significantly increased acidities or basicities of up to ca. 10 p K a units in the excited state compared to the ground state. While organic photobases are either of “single use” in the case of photobase generators or are limited functionally by their UV…
This work presents the synthesis and structural characterization of a novel type of biscyclometalated Ir(III) complex, which is equipped with two iodoethynyl moieties on its 2,2′-bipyridine (bpy) ligand. Iodoethynyl moieties represent prominent donor systems for the formation of supramolecular structures…
Due to their ultra‐high sensitivity, solution‐gated graphene‐based field‐effect transistors (SG‐GFET) have been proposed for applications in bio‐sensing. However, challenges regarding the functionalization of GFETs have prevented their applications in clinical diagnostics so far. Here GFET sensors based…
A strategy of “greening up” Pt(II) luminophores is presented. For this purpose, caffeine, as a renewable alkaloid and precursor for an N ‐heterocyclic carbene (NHC), is incorporated into a tridentate, pincer‐type ligand framework. A series of luminescent Pt(II) complexes, containing the tridentate bis…
A tridentate bis -NHC Pd complex, based on caffeine, was studied for its catalytic activity. This complex displayed a high catalytic activity in the Suzuki–Miyaura and Mizoroki–Heck cross-coupling reactions of aryl halides. The Sonogashira cross-coupling was also investigated but reveals a fast plateauing…
The electrochemistry and photophysics of the Pt(II) complexes [Pt(naphen)(X)] (Hnaphen = naphtho[1,2- b ][1,10]phenanthroline, X = Cl or C≡CPh) containing the rigid tridentate C^N^N -coordinating pericyclic naphen ligand was studied alongside the complexes of the tetrahydro-derivative [Pt(thnaphen)(X)]…
Polyoxymethylene dimethyl ethers (OME n ) are considered as substituents or additives for fossil diesel fuel. Efficiency of the synthesis is crucial for the development of industrial scale production plants. Therefore, the design of suitable catalysts and the efficient heating play important roles in…
N -Heterocyclic carbenes (NHCs) have seen more and more use over the years. The go-to systems that are usually considered are derivatives of benzimidazole or imidazole. Caffeine possesses an imidazole unit and was already utilized as a carbene-type ligand; however, its use within a tridentate bis-NHC…
Nowadays, the study of metallopolymers is one of the fastest growing areas of polymer science. Metallopolymers have great potential for application in multiple technological and various biomedical processes. The macromolecules with the possibility of varying the number and type of metal ions along the…
The contribution deals with the synthesis of the poly(methacrylate)-based copolymers, which contain ferrocene and/or terpyridine moieties in the side chains, and the subsequent analysis of their self-assembly behavior upon supramolecular/coordination interactions with Eu 3+ and Pd 2+ ions in dilute solutions.…
Abstract A homoleptic ethynyl-substituted ruthenium(II)-bisterpyridine complex representing a versatile synthon in supramolecular chemistry was synthesized and analyzed by NMR spectroscopy, mass spectrometry and X-ray diffractometry. Furthermore, its photophysical properties were detailed by UV/Vis absorption,…
