Macromolecule‐Driven Supramolecular Polymerization Induced by Crowding Effects
Angewandte Chemie, EarlyView.A systematic study is presented that investigates the influence of the excluded volume effect by macromolecules on supramolecular polymerizations in organic media. Upon crowding, the discotic supramolecular monomers sequentially assemble into polymers and higher‐order aggregates (HOAs), affected by the macromolecule's concentration, size and polarity ...

Cosmology Due to Thermodynamics of Apparent Horizon
Annalen der Physik, EarlyView.Effective cosmological constant as a function of the Hubble rate H for different entropy parameters b. Figure shows the asymptotic of the effective cosmological constant. At H = 0 the effective cosmological constant vanishes. Abstract This study proposes new entropy of the apparent horizon Sh=(1/β)arctan(βSBH)$S_h=(1/\beta)\arctan (\beta S_{BH ...

Indeno[2,1‐c]fluoren Quasi[8]circulene mittels intramolekularer Cyclisierung
Angewandte Chemie, EarlyView.Eine neue Klasse gewölbter, chiraler polyzyklischer aromatischer Kohlenwasserstoffe entsteht durch die Fusion von Indeno[2,1‐c]fluoren‐ und Quasi[8]circulen‐Motiven. Diese redoxaktiven, antiaromatischen Strukturen bieten eine hohe synthetische Vielseitigkeit, einstellbare Eigenschaften und modulare Funktionalitäten für organische Elektronik und ...

Interfacial Photoelectrochemistry in Organic Synthesis
Angewandte Chemie International Edition, Accepted Article.Photoelectrodes have traditionally enjoyed widespread attention as heterogeneous catalysts for the activation of water and CO2 in energy research, while photoelectrochemistry with homogeneous molecular catalysts dominates the activations of more complex molecules in organic synthesis.
