Single-Crystal Polycationic Polymers Obtained by Single-Crystal-to-Single-Crystal Photopolymerization

Journal of the American Chemical Society, 2020
The efficient preparation of single-crystalline ionic polymers and fundamental understanding of their structure-property relationships at the molecular level remains a challenge in chemistry and materials science. Here, we describe the single-crystal structure of a highly ordered polycationic polymer (polyelectrolyte) and its proton conductivity.

Reversible Thermochromism of Nickel(II) Complexes and Single-Crystal-to-Single-Crystal Transformation

ACS Omega, 2019
A molecular Ni­(II)–NNN pincer complex (1) exhibited unprecedented reversible single-crystal-to-single-crystal transformation and color change upon heating and cooling due to a subtle change in the N–Ni­(II) bond length and ligand conformation.

A-Site Cation Size Effect on Structure and Magnetic Properties of Sm(Eu,Gd)Cr_0.2Mn_0.2Fe_0.2Co_0.2Ni_0.2O₃ High-Entropy Solid Solutions

Nanomaterials, 2021
Three high-entropy Sm(Eu,Gd)Cr0.2Mn0.2Fe0.2Co0.2Ni0.2O3 perovskite solid solutions were synthesized using the usual ceramic technology. The XRD investigation at room temperature established a single-phase perovskite product.

Creation and Magnetic Study of Ferrites with Magnetoplumbite Structure Multisubstituted by Al³⁺, Cr³⁺, Ga³⁺, and In³⁺ Cations

Nanomaterials, 2022
Multisubstituted barium ferrites with a magnetoplumbite structure were obtained by the method of solid-phase reactions with ferritization and pre-firing. Three-charged, mainly diamagnetic cations Al3+, Cr3+, Ga3+, and In3+ were chosen as substituents for

Polysubstituted High-Entropy [LaNd](Cr_0.2Mn_0.2Fe_0.2Co_0.2Ni_0.2)O₃ Perovskites: Correlation of the Electrical and Magnetic Properties

Nanomaterials, 2021
La-, Nd- and La/Nd-based polysubstituted high-entropy oxides (HEOs) were produced by solid-state reactions. Composition of the B-site was fixed for all samples (Cr0.2Mn0.2Fe0.2Co0.2Ni0.2) with varying of A-site cation (La, Nd and La0.5Nd0.5).

Single crystal to single crystal transformations [PDF]

Australian Journal of Chemistry, 2006
The past decade has witnessed escalating interest in solidstate phase transitions that involve significant changes in structure without appreciable loss of crystal mosaicity— single crystal to single crystal (SC-SC) transformation.[1–5] Several factors have contributed to these studies: increased general access to X-ray diffraction facilities ...
