Designing a new family of oxonium-cation based structurally diverse organic–inorganic hybrid iodoantimonate crystals

Abstract

We report proton-bound oxonium cation based iodoantimonate hybrid organic–inorganic crystals with diverse structure–property relationships.

An Organic–Inorganic Perovskitoid with Zwitterion Cysteamine Linker and its Crystal–Crystal Transformation to Ruddlesden‐Popper Phase

“…Indeed, these 2D systems have already been demonstrated to possess several unique properties such as moisture stability, thermal stability, self‐trapping of excitonic features, and long carrier lifetimes. These properties make them highly applicable for LEDs, lasing, and white‐light emission applications as well [13–20] . The 2D lead based HOIPs (tolerance factor, t >1) can form Ruddlesden Popper (RP) type phase (general formula: A n +1 B n X 3 n +1 ), Dion‐Jacobson type perovskite phase (general formula: A′A n −1 Pb n X 3 n +1 ) or alternating cation type phase (general formula: (A′A) n +1 B n X 3 n +1 ) by incorporation of long alkyl/aryl‐organic monovalent or divalent cations, respectively [21] .…”

[21] Also,insome cases some degree of strain is imparted to the MX 6 À octahedra from the organic cations,which leads to distorted octahedra, giving rise to some uniquely interesting electronic density of states and properties.M ao et al have reported ac orrugated 2D hybrid perovskite (DMEN)PbBr 4 (2-(Dimethylamino)ethylamine lead bromide), which exhibited broadband white light emission with an impressive colour rendering index (CRI) value of 73.…”

Expanded graphite incorporated with Li4Ti5O12 nanoparticles as a high-rate lithium-ion battery anode

“…11 Various strategies have been researched, including chemical oxidation, surface coating treatment, and porous-structure design. [12][13][14][15][16][17][18][19] By coating an arti-cial Li + conductor on the graphite surface, the interface Li + diffusion resistance could be obviously decreased, resulting in an enhanced kinetic character. 20 Lee et al applied Li 4 Ti 5 O 12 (LTO) as a coating layer for MCMB (middle phase carbon microsphere) surface modication, achieving smaller interface resistance than that of the original MCMB aer 40 cycles, due to the LTO layer inhibiting the successive decomposition of electrolyte at the electrode/electrolyte interface during long cycles.…”

Nano-laponite/polymer composite as filtration reducer on water-based drilling fluid and mechanism study

“…Due to the protonation of Mg-OH in nano-laponite flakes, the edges of the nano-laponite particles become positively charged in water ( pH < 11). Hydrolysis of KH570 in an aqueous ethanol solution produces Si-OH, which combines with the asymmetric stretching vibration peak of -OH at the edges of nano-laponite to modify the nano-laponite [45][46][47].…”
