Charge polarity-dependent ion-insertion asymmetry during electrochemical doping of an ambipolar π-conjugated polymer

Nature Communications, 2022
The influence of ion-sidechain interactions on ion-insertion energetics in organic mixed ionicelectronic conductors (OMIECs) is not well understood. The authors show that a Gutmann Donor/Acceptor number framework captures ion-sidechain interactions and ...

Base-Catalyzed Polymerization of a Substituted Methylenebicyclo[3.3.1]nonane

International Journal of Polymer Science, 2023
Lignite humic acid on reaction with formaldehyde and aqueous alkali led to a polybicyclo[3.3.1]nonane. This was characterized spectroscopically using mass spectrometry, FT-IR, powder X-ray diffraction, TEM, and NMR studies (1H-NMR, CP-MAS-SS-NMR) which ...

Band Gap Reduction in Ferroelectric BaTiO3 Through Heterovalent Cu-Te Co-Doping for Visible-Light Photocatalysis

Frontiers in Chemistry, 2021
It is believed that ferroelectrics may serve as efficient photocatalysts as well as photovoltaic materials but for their large bandgaps which does not allow them to absorb a large part of the solar spectrum.

Parallel triplet formation pathways in a singlet fission material

Nature Communications, 2022
The singlet fission mechanism is still not relatively well understood, except for polyacenes. Here, the authors demonstrate that in diketopyrrolopyrrole supramolecular assemblies, both singlet fission and intersystem crossing can simultaneously happen.

Modulation-doping a correlated electron insulator

Nature Communications, 2023
Correlated electron materials (CEMs) host a rich variety of condensed matter phases. Vanadium dioxide (VO2) is a prototypical CEM with a temperature-dependent metal-to-insulator (MIT) transition with a concomitant crystal symmetry change.

Quaternary and quinary molecular solids based on structural inequivalence and combinatorial approaches: 2-nitroresorcinol and 4,6-dichlororesorcinol

IUCrJ, 2021
A synthetic strategy for the formation of stoichiometric quaternary and nonstoichiometric quinary solids is outlined. A series of 2-nitroresorcinol-based quaternary cocrystals were developed from binary precursors in two conceptual stages.

Four- and five-component molecular solids: crystal engineering strategies based on structural inequivalence

IUCrJ, 2016
A synthetic strategy is described for the co-crystallization of four- and five-component molecular crystals, based on the fact that if any particular chemical constituent of a lower cocrystal is found in two different structural environments, these ...
