Platinum(II) complexes of aryl guanidine-like derivatives as potential anticancer agents: between coordination and cyclometallation
(2025)The preparation of a wide variety of Pt(II) complexes with aryl guanidines and their potential application as anticancer agents have been explored. A relatively facile synthesis of cyclometallated Pt(II) complexes of ... -
Synthesis and Characterization of a Masked Terminal Nickel-Oxide Complex
(2023)In exploring terminal nickel-oxo complexes, postulated to be the active oxidant in natural and non-natural oxidation reactions, we report the synthesis of the pseudo-trigonal bipyramidal NiII complexes (K)[NiII(LPh)(DMF)] ... -
Evidence for a High-Valent Iron-Fluoride That Mediates Oxidative C(sp3)-H Fluorination
(2023)[FeII(NCCH3)(NTB)](OTf)2 (NTB = tris(2-benzimidazoylmethyl)amine, OTf = trifluoromethanesulfonate) was reacted with difluoro(phenyl)-λ3-iodane (PhIF2) in the presence of a variety of saturated hydrocarbons, resulting in ... -
Aromatic and aliphatic hydrocarbon hydroxylation via a formally NiIV=O oxidant
(2023)The reaction of (NMe4)2[NiII(LPh)(OAc)] (1[OAc], LPh = 2,2′,2′′-nitrilo-tris-(N-phenylacetamide); OAc = acetate) with 3-chloroperoxybenzoic acid (m-CPBA) resulted in the formation of a self-hydroxylated NiIII-phenolate ... -
Manganese oxide nanosheets and a 2D hybrid of graphene-manganese oxide nanosheets synthesized by liquid-phase exfoliation
(2015)Manganese oxide nanosheets were synthesized using liquid-phase exfoliation that achieved suspensions in isopropanol with concentrations of up to 0.45 mg ml-1. A study of solubility parameters showed that the exfoliation ... -
Trendbericht Organische Chemie 2023
(2023)Polystyrolproben werden mit Eisen(III)chlorid und weißen LEDs zu Oligomeren und Benzoylprodukten; ein Wolframatkatalysator invertiert die Absolutkonfiguration an sp3-Kohlenstoffzentren; gelöstes Rätsel um eine symmetrieverbotene ... -
Bicyclo[1.1.1]pentane Embedded in Porphyrinoids**
(2023)We report a two-step approach to obtain synthetically versatile bicyclo[1.1.1]pentane (BCP) derivatives using Grignard reagents. This method allows the incorporation of BCP units in tetrapyrrolic macrocycles and the ... -
Molecular Symmetry and Art: Visualizing the Near-Symmetry of Molecules in Piet Mondrian's De Stijl
(2024)Symmetry and shape are essential aspects of molecular structure and how we interpret molecules and their properties. We, as chemists, are comfortable with pictorial representations of structure, in which some nuance is ... -
Chirality induction to porphyrin derivatives co-confined at the air-water interface with silica nano-helices: towards enantioselective thin solid film surfaces
(2024)A supramolecular approach based on self-assembled structures allows the formation of large structured co-assemblies based on chiral and achiral compounds with original physicochemical features. In this contribution, an ... -
Trendbericht Organische Chemie 2024
(2024)Unter anderem das hat die Organik im letzten Jahr bewegt: milde Oxidation mit Elektrochemie, Oxidation zu enantiomerenreinen Sulfonylverbindungen, Flüssigkristallphasen erkennen mit maschinellem Lernen, CO2 reagiert zu ... -
Quantifying near-symmetric molecular distortion using symmetry-coordinate structural decomposition
(2024)We imagine molecules to be perfect, but rigidified units can be designed to bend from their ideal shape, discarding their symmetric elements as they progress through vibrations and larger, more permanent distortions. The ... -
Functional organic adlayers for controlling the adhesion strength of electrolessly deposited copper on super-engineering plastics
(2025)Effective metallization of super-engineering plastics such as liquid crystal polymers (LCP) and polyphenylene sulfides (PPS) via electroless deposition of copper thin films is an important step in the manufacturing of a ... -
Porphyrin Atropisomerism as a Molecular Engineering Tool in Medicinal Chemistry, Molecular Recognition, Supramolecular Assembly, and Catalysis
(2024)Porphyrin atropisomerism, which arises from restricted σ-bond rotation between the macrocycle and a sufficiently bulky substituent, was identified in 1969 by Gottwald and Ullman in 5,10,15,20-tetrakis(o-hydroxyphenyl)porphyrins. ... -
Synthesis, biological evaluation, and docking studies of pyrazole-linked benzothiazole hybrids as promising anti-TB agents
(2024)Tuberculosis (TB) is a global pandemic killing millions of people every year. Yet, resistant strains make curing TB quite challenging. Herein, a series of new pyrazole-linked benzothiazole hybrids was synthesized and ... -
C–C Coupling in sterically demanding porphyrin environments
(2024)Unlike their planar counterparts, classic synthetic protocols for C–C bond forming reactions on nonplanar porphyrins are underdeveloped. The development of C–C bond forming reactions on nonplanar porphyrins is critical in ... -
Fine-tuning of radiative properties by “mild” substituents: searching for a perfectly soft chromophore
(2024)Controlling spectral properties to achieve desired characteristics is an attractive goal in application- oriented research, e.g., in the design of fluorescence sensors. ‘‘Soft’’ chromophores, molecules with strong spectral ... -
Understanding and Controlling Molecular Compositions and Properties in Mixed-Linker Porphyrin Metal-Organic Frameworks
(2024)Porphyrin-based metal-organic frameworks (MOFs) are attractive materials for photo- and thermally activated catalysis due to their unique structural features related to the porphyrin moiety, guest accessible porosity and ... -
Antitumor Immunity Mediated by Photodynamic Therapy Using Injectable Chitosan Hydrogels for Intratumoral and Sustained Drug Delivery
(2024)Photodynamic therapy (PDT) is an anticancer therapy with proven efficacy; however, its application is often limited by prolonged skin photosensitivity and solubility issues associated with the phototherapeutic agents. ... -
