Three distinct conductance states in polycyclic aromatic hydrocarbon derivatives
Royal Society Open ScienceTight-binding model (TBM) and density functional theory (DFT) calculations were employed. Both simulations have demonstrated that the electrical conductance for eight polycyclic aromatic hydrocarbons (PAHs) can be modulated by varying the number of ...

Carbon Energy, EarlyView.This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

Chemistry – A European Journal, EarlyView.A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.

Chemistry – A European Journal, EarlyView.Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Chemistry – A European Journal, EarlyView.Reactions of 10‐mesityl‐1,8‐diphenylanthracene with DDQ/TfOH produced three products via sequential formation of a five‐ or seven‐membered ring. Unexpectedly, the triply cyclized product with a rubicene substructure was formed through cyclization involving 1,2‐methyl shift.
