Thermally Controlled Chiral Supramolecular Polymorphism in Water

open access: yesAngewandte Chemie International Edition, EarlyView.
Using an amphiphilic oligo(phenyleneethynylene) derivative, we establish LCST‐coupled chirality as a strategy to regulate thermoresponsive supramolecular polymorphism in water. At room temperature, AggI forms discrete assemblies that transform into elongated helical fibers (AggII) near the LCST and subsequently to sheet‐like structures (AggIII) at ...

Forcing the Side‐on π‐Coordination of a C≡C Triple Bond to Technetium Using the As,CC,As Alkyne Pincer Ligand 1,2‐Bis(2‐(diisopropylarsaneyl)‐4‐(trifluoromethyl)phenyl)Ethyne

open access: yesAngewandte Chemie International Edition, EarlyView.
Technetium alkyne complexes have eluded isolation for decades with the only indicators for their existence being the isolation of vinylidene carbenes or their follow‐up reaction products despite plentiful of reports for neighboring elements. Stable, crystalline Tc(III) and Tc(V) alkyne complexes (and their Re analogs) have now been prepared and fully ...
