β‐Ketonitrile‐Modified Prodan Derivatives as Large‐Stokes‐Shift Solvatochromic Fluorophores With Enhanced Brightness and Ratiometric Thermometric Response

open access: yesChemistry – A European Journal, EarlyView.
We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.

Molekulare Solarthermiespeicher—zwei Fallstudien zur Optimierung Molecular solar thermal storage—two case studies on optimization

open access: yesChemie Ingenieur Technik, EarlyView.
Molekulare Solarthermiespeicher (MOST) überführen Licht in Wärmeenergie, die zu einem späteren Zeitpunkt genutzt werden kann. Die Optimierung solcher Systeme wird von vielen Parametern bestimmt, wie hier an zwei Beispielmolekülklassen, Azobenzole und Azaborinine, gezeigt.

Auto‐Click Synthesis of a Copper(I)–N‐Heterocyclic Carbene Porous Organic Polymer and Its Transmetalation to Palladium(II) for Azide–Alkyne Cycloaddition and Cross‐Coupling Reactions

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
An azide‐functionalized Cu(I)–NHC complex acts as both a monomer and a catalyst in an auto‐click polymerization, yielding a Cu(I)–NHC polymer that can be transmetalated to Pd(II). The two materials catalyze copper‐catalyzed azide–alkyne cycloaddition, C–N/C–O coupling, and Suzuki–Miyaura reactions, while copper reloading restores activity.

Imidazolium Modified UiO‐67 Metal‐Organic Frameworks for CO2 Adsorption

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
CO2 sorption in UiO‐67 and its imidazolium‐functionalized derivatives is examined with emphasis on the role of different counterions. Structural characterization and spectroscopic studies provide insight into how functionalization affects pore environments and CO2 interactions.

Variously Substituted Cyclopenta[2,1‐b:3,4‐b’]difluorenyl Radicals: A Validation of Clar's Rule

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Clar's empiric rule implies that the most contributing resonance formula is that with the maximum number of fully intact benzene rings. This is now further supported experimentally by the synthesis of two further, differently substituted cyclopenta[2,1‐b:3,4‐b’]difluorenyl radicals.
