DOI: 10.1002/aenm.202405364

Abstract: Glassy metal–organic frameworks (MOFs) featured with excellent ionic conductivity and processability have attracted tremendous attention, yet remaining unexplored for electrocatalytic 5‐hydroxymethylfurfural (HMF) oxidation. Herein, developed as the first example of glassy MOFs for electrocatalytic HMF… read more here.

DOI: 10.1021/acs.macromol.6b02540

Abstract: A chemiluminescent mechanophore, bis(adamantyl-1,2-dioxetane), is used to investigate the covalent bond scission resulting from the sorption of chloroform by glassy poly(methyl methacrylate) (PMMA) networks. Bis(adamantyl)-1,2-dioxetane units incorporated as cross-linkers underwent mechanoluminescent scission, demonstrating that solvent… read more here.

DOI: 10.1021/acsmacrolett.2c00238

Abstract: Molecular force transduction in tough and glassy poly(meta,meta,para-phenylene) (PmmpP) was investigated as a function of Mn using covalently incorporated mechanochromic donor-acceptor torsional springs based on an ortho-substituted diphenyldiketopyrrolopyrrole (oDPP). Blending oDPP-PmmpP probe chains with long… read more here.

DOI: 10.1039/c8sm00968f

Abstract: Motivated by recent observations that non-concatenated ring polymers in their dense solution exhibit a glass-like dynamics, we propose a free volume description of the motion of such rings based on the notion of topological volume.… read more here.

DOI: 10.1039/d5sm00929d

Abstract: The selective reflection and circular polarization characteristics of cholesteric liquid crystals (CLCs) arise from their self-assembly into helicoidal structures, producing photonic stopbands typically 50-100 nm wide. Here, we demonstrate that thermal annealing of enantiomeric cholesteric… read more here.
