Special Issue Information

Dear Colleagues,

Organometallic chemistry has become an impactful area of chemistry and is employed in many areas of chemistry. Organometallic chemistry is now as vibrant and exciting as ever, with research impacting photo-, electro-, and thermal catalysis, main-group chemistry, chemical biology, lanthanides and actinides, organic synthesis, and materials science. For instance, luminescent organometallic compounds are broadly used to produce electroluminescent devices, fluorescent sensors, and labels for the visualization of biological structures and processes and in oxygen mapping and generation of singlet oxygen, drug delivery tracking, sensing of different ions in the solution, and sensing of small molecules. There is no limit to the applications of organometallic chemistry. Organometallic chemistry is involved in constructing cage compounds, coordination polymers, MOFs, supramolecular systems, nanostructured materials, nanotechnology, molecular magnets, and many more.

Hence, this Special Issue, celebrating the 10th Anniversary of Inorganics intends to bring the role of organometallic chemistry and related applications into the spotlight, thus allowing readers to appreciate organometallic chemistry as a paramount area of chemical sciences that is intertwined with many other fields ranging from industrial to medical applications to nanotechnology. This Special Issue offers the unique opportunity for exchange between scientists and researchers in organometallic chemistry in mostly chemistry (inorganic and organic), (bio)medicinal chemistry, polymer chemistry, metallocene, industrial chemistry, catalysis, material, and nanotech fields. Communications, original research and comprehensive review papers, and perspectives contributing to the field are welcome.

Novel organometallic complexes Mn(benzene-1,2-diamine)(CO)3Br, Mn-1, Mn(3-methylbenzene-1,2-diamine)(CO)3Br, Mn-2, and Re(benzene-1,2-diamine)(CO)3Cl, Re-1, have been synthesized and characterized by IR, UV/Vis, 1H-NMR, EA and HRMS. The structures of Mn-2 and Re-1 were confirmed by X-ray crystallography. The three novel compounds were studied for their electrocatalytic reduction of carbon dioxide to carbon monoxide using cyclic voltammetry in acetonitrile solutions. Controlled potential electrolysis was used to obtain information on faradaic yield, with product formation being confirmed by GC. Using earth-abundant manganese, compounds Mn-1 and Mn-2 display turnover frequencies of 108 s−1 and 82 s−1, respectively, amid selective production of carbon monoxide (faradaic yields ~85%), with minimal co-production of dihydrogen (<2%), and low overpotential of 0.18 V. The rhenium congener, Re-1, displays no activity as an electrocatalyst for carbon dioxide reduction under identical conditions. Full article

Carbon dots (CDs) are zero-dimensional nanomaterials composed of carbon and surface groups attached to their surface. CDs have a size smaller than 10 nm and have potential applications in different fields such as metal ion detection, photodegradation of pollutants, and bio-imaging, in this review, the capabilities of CDs in metal ion detection will be described. Quantum confinement is generally viewed as the key factor contributing to the uniqueness of CDs characteristics due to their small size and the lack of attention on the surface functional groups and their roles is given, however, in this review paper, the focus will be on the functional group and the composition of CDs. The surface functional groups depend on two parameters: (i) the oxidation of precursors and (ii) their composition. The mechanism of metal ion detection is still being studied and is not fully understood. This review article emphasizes the current development and progress of CDs, focusing on metal ion detection based on a new perspective. Full article

Title: Luminescent diimine-Pt(IV) complexes with axial phenyl selenide ligands
Authors: Marzieh Dadkhah Aseman; Reza Babadi Aghakhanpour; Zohreh Sharifioliaei; Masoud Nabavizadeh; Axel Klein
Affiliation: Tarbiat Modares University
Abstract: Luminescent diimine-Pt(IV) complexes [Pt(N^N)(Me)2(PhSe)2], (N^N = 2,2ʹ-bipyridine (bpy, 1b), 1,10-phenanthroline (phen, 2b), and 4,4ʹ-dimethyl-2,2ʹ-bipyridine (Me2bpy, 3b), PhSe‒ = phenyl selenide, were prepared and identified by multinuclear (1H, 13C{1H} and 77Se{1H}) NMR spectroscopy. The PhSe‒ ligands are introduced by oxidative addition of diphenyl diselenide to the non-luminescent Pt(II) precursors [Pt(N^N)(Me)2], N^N = (bpy, 1a), (phen, 2a), (Me2bpy, 3a), to give the luminescent Pt(IV) complexes 1b to 3b. The UV-vis absorption spectra of 1b to 3b are characterised by strong bands in the range 240 to 330 nm, assigned to transitions of essentially π‒π* character with admixtures from metal and PhSe‒ ligand contributions with the help of TD-DFT (time-dependent density functional theory) calculations. Also, the weak long-wavelength bands in the range 350 to 475 nm are of mixed ligand-to-metal charge transfer (LʹMCT) (n(Se)d(Pt) / intra-ligand charge transfer (ILʹCT) (n(Se)π*(Ph) or π(Ph)π*(Ph))/ ligand-to-ligand’ charge transfer (LLʹCT) (L = N^N, Lʹ = PhSe‒, M = Pt and n = lone pair) character. The Pt(IV) complexes showed broad emission bands in the solid state at 298 and 77 K peaking at 560 to 595 nm with a blue-shift upon cooling. Structured emission bands were obtained in the range 450 to 600 nm with maxima depending on the N^N ligands and the solvent polarity (CH2Cl2 vs. dimethyl sulfoxide (dmso) and aqueous tris(hydroxymethyl)aminomethane hydrochloride (tris-HCl) buffer). The emissions stem from essentially ligand-centred triplet states (3LC) with mixed π‒π*, LʹLCT and ILʹCT character and small admixtures of LʹMCT and MLCT contributions.

Affiliation: 1 China-UK Low Carbon College, Shanghai Jiao Tong University; 2 School of Mechanical Engineering, Shanghai Jiao Tong University
Abstract: Emerging as a new class of advanced functional materials with hierarchical architectures and re-dox characters, the organic-inorganic hybrids have been well developed and widely applied in various applications recently. In this review, we focus on the applications and struc-ture-performance relationship of organic-inorganic hybrids for electrochemical water splitting. The general principles of water oxidation will be firstly presented, followed by the progresses on the applications of organic-inorganic hybrids that are classified as MOFs and their derivates, COFs-based hybrids and other organic-inorganic hybrids. The roles of organic counterparts on catalytic active centers will be fully discussed and highlighted with typical examples. Finally, the challenges and perspectives assessing of this promising hybrid materials as electrocatalysts will be provided.

Title: Mono-alkyl-substituted phosphinoboranes (HRP–BH2–NMe3) as precursors for poly(alkylphosphinoborane)s: improved synthesis and comparative study
Authors: Felix Lehnfeld; Tim Oswald; Rüdiger Beckhaus; Manfred Scheer
Affiliation: University of Regensburg
Abstract: A new synthetic pathway to various mono-alkyl-substituted phosphinoboranes HRP–BH2–NMe3 has been developed. The new synthetic route starting from alkyl halides and NaPH2 followed by metalation and salt metathesis is performed in a one-pot procedure and leads to higher yields and purity of the resulting phosphinoboranes as compared to previously reported routes. Addition-ally, the scope of accessible compounds could be expanded from short-chained linear alkyl sub-stituents to longer chained linear alkyl substituents as well as secondary or functionalized alkyl substituents. The reported examples include primary alkyl-substituted phosphinoboranes RHP-BH2-NMe3 (R = n-butyl, n-pentyl, n-hexyl; 1a-c), the secondary alkyl-substituted derivatives iPrPH-BH2-NMe3 (2) and the functionalized alkyl-substituted 4-bromo-butyl-phosphinoborane (BrC4H8)PH-BH2-NMe3 (3). Compounds 1a, 1c and 2 were additionally used for preliminary polymerization reactions via a thermal and a transition metal-catalyzed pathway, revealing the formation of high molecular weight polymers under certain conditions. Detailed investigations on the influence of temperature, concentration, substituents and reaction time on the respective polymerization reactions were performed.
