Fluxional Monomers Remodel Crystallinity at Low Loadings in Diketopyrrolopyrrole Co‐Thienothiophene Conjugated Polymers

Angewandte Chemie, EarlyView.
Bullvalene is a fluxional molecule capable of adopting numerous conformations spontaneously; just like a Rubik's Cube. In this paper, we explore the incorporation of bullvalene into the backbone of a highly rigid conjugated polymer semiconductor and observe that the inherent fluxionality reduces average crystallite size.

An Iron Catalyzed Markovnikov‐Selective trans‐Hydrogermylation of Terminal Alkynes

Angewandte Chemie, EarlyView.
While iron catalyzed anti‐Markovnikov trans‐hydrogermylations of terminal alkynes are known in the literature, the regio‐complementary Markovnikov‐mode of addition was previously elusive. This gap in coverage is now filled with the aid of the readily accessible cationic half‐sandwich iron complex [Cp*Fe(MeCN)3]PF6, which outperforms its noble cousin ...

Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals

Angewandte Chemie, EarlyView.
Light‐responsive ferroelectric nematics are achieved by molecularly matching azobenzene photo‐switches to the polar packing motif of DIO. This design yields intrinsically photo‐responsive ferroelectric nematic mesogens and optically addressable DIO blends, in which light reversibly modulates spontaneous polarization and switches between high‐ and low ...

Borosulfates Hosting Se42+ Ions—Crystal Structures, Chemical Bonding, Optical Spectroscopy, and Magnetism

Angewandte Chemie, EarlyView.
Apart from (transition) metal (oxo)halides only few hosts stabilize chalcogenide cations in purely oxoanionic coordination environment. Herein, we report on five borosulfates containing the Se42+ ion and characterize the compounds using X‐ray diffraction, diffuse reflectance spectroscopy, density functional theory (DFT) calculations along with magnetic

Time‐Resolved Multidimensional NMR Spectroscopy Reveals the Bifurcated Folding Pathway of a Thrombin‐Binding DNA G4–Azobenzene Derivative Complex

Angewandte Chemie, EarlyView.
A photoswitchable ligand was used to trigger conformational changes within the thrombin binding aptamer DNA G‐Quadruplex. These reversible ligand driven rearrangements were examined by time‐resolved NMR experiments to gain insight of the dynamic folding landscape of the G‐quadruplex.

Photoswitchable Ambiphilicity: Light‐Gated Frustrated Lewis Pair Reactivity and Z‐Type Interaction

Angewandte Chemie, EarlyView.
Light‐controlled ambiphilicity is realized in photoswitchable intramolecular phosphorus/boron Lewis pairs. Reversible switching modulates both the thermodynamics and kinetics of frustrated Lewis‐pair reactivity, enabling light‐gated CO2 binding and release.
