Dipolar Molecular Motor Candidates with Planar Chirality

Chemistry – A European Journal, EarlyView.
Two prototypes of molecular motors with simultaneous implementation of planar chirality and a permanent dipole have been designed and synthesized in 7 steps with overall yields of 2.8 to 5.5%. Abstract Two molecular motor candidates built around ruthenium(II) centers featuring both planar chirality and a permanent dipole have been synthesized in seven ...

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Mechanistic Insights and Catalytic Efficiency of a 2,2′‐Bipyridine–Coordinated Peroxidovanadium Complex as a Haloperoxidase Biomimetic

ChemPlusChem, EarlyView.
A peroxidovanadium(V) complex mimics vanadium haloperoxidases for eco‐friendly halogenation of organic substrates. Density functional theory studies reveal two major reaction pathways for iodide/bromide oxidation. The catalyst offers high‐yield bromination/iodination of 8‐hydroxyquinoline (73/86%) under mild conditions (30 °C, pH 5.8), and it also ...

Electrochemical Characterization of Site‐Specifically Metal‐Modified DNA Films on Gold Electrode Surfaces

ChemPlusChem, EarlyView.
DNA films containing different CuII‐ or AgI‐mediated base pairs are investigated with respect to their electrochemical properties and how these depend on the size and charge of the artificial metal‐binding nucleobase as well as the location of the metal‐mediated base pair within the duplex.

Switchable Intersystem Crossing (sISC) in Organic Dyes: Unlocking Dynamic Photonic Properties

ChemPhotoChem, EarlyView.
This Concept article introduces switchable intersystem crossing (sISC) as an emerging design strategy for functional dyes capable of reversibly modulating fluorescence and triplet state formation in response to environmental stimuli. Key design approaches and underlying mechanisms are discussed, alongside representative examples of sISC dyes and their ...

Squamate ventricular cardiomyocytes: Ploidy, proliferation, and heart muscle cell size in the leopard gecko (Eublepharis macularius)

Developmental Dynamics, EarlyView.
Abstract Background While heart function is broadly conserved across vertebrates, the cellular phenotype of muscle cells (cardiomyocytes) varies across taxa and throughout ontogeny. Emerging evidence suggests that some attributes may correlate with the capacity for spontaneous cardiomyocyte replacement following injury.
