Usage

Description

Methanamine, N-methyl-, hydrobromide (9CI), also known as Dimethylammonium bromide (DMABr), is a compound characterized by its larger cationic nature. It is commonly used in the field of hybrid organic-inorganic electronics applications, particularly for tuning the band-gap or electrical properties of perovskite structures.

Uses

Used in Electronics Industry:
Methanamine, N-methyl-, hydrobromide (9CI) is used as a tuning agent for perovskite structures to enhance their band-gap and electrical properties. This application is crucial for achieving highly efficient device performance and longer lifetime stability in hybrid organic-inorganic electronics.
Additionally, Methanamine, N-methyl-, hydrobromide (9CI) serves as a precursor to Nitrosodimethylamine (N525625), a potent carcinogen that is produced during the disinfection of wastewater effluent. It is also present in trace amounts in food and polluted air, and can be found in human urine, where its presence may indicate certain disorders. However, this application is not directly related to the primary use of DMABr in the electronics industry.

7Pb4X15 (X = Cl- and Br-), 2D-Perovskite Related Hybrids with Dielectric Transitions and Broadband Photoluminiscent Emission

We have prepared two new lead halides with the novel general formula of DMA7Pb4X15 (DMA = [(CH3)2NH2]+ and X = Cl- or Br-) by using an easy route under mild conditions at room temperature. These compounds exhibit an unprecedented crystal structure, are formed by layers of distorted [PbX6] octahedra, which share corners and faces, and contain intercalated DMA cations. Very interestingly, they display dielectric transitions, which are related to a partial order-disorder process of the DMA cations between 160 and 260 K. Additionally, these new layered hybrids exhibit a broadband photoluminiscent emission, which is related to the structural distortions of the [PbX6] octahedra. These findings not only open up large possibilities for future optoelectronic applications of these materials, but they also offer a novel playground for an easy modulation of electrical and optical properties of hybrid organic-inorganic materials. We anticipate that this novel A7Pb4X15 formula can be adequate to tune the family of the hybrid lead halides using other alkylammonium cations, such as methylammonium, formamidinium, or ethylammonium, to improve their photoelectronic properties.

Di-, tri-, and tetra(pentafluorophenyl) derivatives for oligotopic anion-π interactions

The present study describes a series of pentafluorobenzyl ammonium salts with two, three, or four C6F5 units in order to investigate simultaneous interactions of several perfluorinated arenes with anions in the crystalline state. Most of the structures show multiple anion-π contacts. However, only 6·2HI reveals an effective encapsulation of the iodide ion by the aromatic units. For comparison, the structure of 4b is investigated because it offers two π-systems with inverse charge distribution to a bromide anion. Only the electron-deficient π-system of the pentafluorophenyl group interacts with the anion.

Photodegradative surfactants: Photolysis of p-dodecylbenzyltrimethylammonium bromide in aqueous solution

Upon UV irradiation, a benzyl-containing cationic surfactant, p-dodecylbenzyltrimethylammonium bromide, has been converted to a nonsurfactant, which can be separated from the aqueous solution by coprecipitation with CaSO4.
