Dynamic Liquid Crystal Elastomers for Body Heat‐ and Sunlight‐ Driven Self‐Sustaining Motion via Material‐Structure Synergy

open access: yesAngewandte Chemie, EarlyView.
Diels–Alder bond‐crosslinked liquid crystal elastomers with low nematic‐to‐isotropic transition temperatures and high reprogrammability were developed, enabling low‐energy, self‐sustained actuators through material‐structure synergy. These actuators achieve high strain rates around 30 °C, facilitating self‐sustaining motion powered by ambient/body heat

Advances and Challenges in Low‐Temperature Upcycling of Waste Polyolefins via Tandem Catalysis

open access: yesAngewandte Chemie, EarlyView.
This review presents an overview of recent advances in mild catalytic transformations of polyolefins, emphasizing the kinetic and thermodynamic interplay between endothermic C─C bond cleavages and the exothermic formation of new C─H, C─C, and C─O bonds.

Supramolecular Gels as Active Tools for Reaction Engineering

open access: yesAngewandte Chemie, EarlyView.
The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Improving Circularity via Chemical Recycling to all Rings

open access: yesAngewandte Chemie, EarlyView.
The initial monomer free energy of polymerization (∆GROP) is traditionally regarded as the benchmark for the polymer's chemical recyclability. But if we instead consider every ring size present at equilibrium (∆GRCE), a different viewpoint emerges. We found that polymers previously regarded as unsuitable for chemical recycling are highly chemically ...

Four‐Centre, Multielectron Bonding in Rare‐Earth Germole Sandwich Complexes

open access: yesAngewandte Chemie, EarlyView.
Stepwise one‐ and two‐electron reduction of the dimeric germole‐ligated sandwich complexes [(η5‐CpGe)M(η5‐Cpttt)]2 (M = Y, Gd, Dy) produces the isostructural complex anions [{(η5‐CpGe)M(η5‐Cpttt)}2]− and [{(η5‐CpGe)M(η5‐Cpttt)}2]2−, respectively. The additional electrons populate bonding molecular orbitals extending across the {M2Ge2} rings, resulting ...
