Arylene Ethynylene Macrocycles with Intramolecular π−π Stacking [PDF]

open access: yes, 2016
Arylene ethynylene macrocycles containing 9,10-anthrylene or 1,4-naphthylene units were synthesized. In chloroform, significant resonance upfield shifting was observed with β-protons of anthrylene and naphthylene in NMR spectra.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

1-[({5-[(4-Methylphenoxy)methyl]-4-phenyl-4H-1,2,4-triazol-3-yl}sulfanyl)methyl]-1H-benzo[d][1,2,3]triazole

open access: yesIUCrData, 2016
The title molecule, C23H20N6OS, adopts a cup-shaped conformation with the planes of the two benzene rings and the benzotriazole unit close to being parallel. The crystal packing features C—H...π(ring) and offset π–π stacking interactions.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Role of molecular packing in RTP features of positional isomers: The case study of triimidazo-triazine functionalized with ethynyl pyridine moieties

open access: yesNext Materials
Organic materials characterized by multi-component emissive behavior including RTP features are extremely desirable for various applications. Frequently, long lasting emissions of solids are originated from intermolecular interactions whose role is far ...

N′-[(1Z)-1-(3-Methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-ylidene)ethyl]-2-[(4-methylphenyl)sulfanyl]acetohydrazide

open access: yesIUCrData, 2017
In the title compound, C21H22N4O2S, the dihedral angle between the pyrazole ring and adjacent benzene ring is 6.4 (1)°. The molecular conformation is influenced by intramolecular N—H...O and C—H...O hydrogen bonds.

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...
