Symmetry-breaking phase transitions, dielectric and magnetic properties of pyrrolidinium-tetrahalidocobaltates

Abstract

We report the physicochemical characteristics of novel Co-based pyrrolidinium analogs: (C4H10N)2CoCl4 (PCC) and (C4H10N)2CoBr4 (PCB). Both compounds consist of the zero-dimensional (OD) anionic network and disordered pyrolidinium cations. The structural...

Tin-based organic–inorganic metal halides with a reversible phase transition and thermochromic response

“…[31][32][33][34] Meanwhile, low-dimensional materials can provide a large degree of freedom for organic ammonium, thereby triggering the order-disorder phase transition. [35][36][37][38] As an example, Zou et al…”

Dual dielectric-responsive hybrid materials with fluorescent properties

“…[1][2][3][4][5] Multi-functional materials possess the capability to integrate a variety of physical signals (such as electrical, magnetic, optical, and thermal) into one device. [6][7][8][9][10][11][12][13] Therefore, they have acted as a significant component in sensors, switches, digital processing systems, and optoelectronic devices, and have shown great potential in meeting the diverse needs of the market. [14][15][16][17][18][19] As functional materials, there has been increasing interest in solid-solid phase transition materials due to their unique properties.…”

Tunable phase transition temperature and nonlinear optical properties of organic–inorganic hybrid perovskites enabled by dimensional engineering

“…The chemical and structural flexibility of organic-inorganic hybrid materials offers the possibility of modulating their physiochemical properties. [1][2][3][4][5][6][7][8][9] As a prominent representative branch, two-dimension (2D) organic-inorganic hybrid perovskite (OIHP) materials, [10][11][12][13][14][15][16][17][18][19][20][21] possessing photophysical characteristics, have been become research hotspots. However, most of the reported materials with only a single property do not meet the current scientific and technological needs.…”
