Phase Transition, Dielectric Properties, and Ionic Transport in the [(CH3)2NH2]PbI3 Organic-Inorganic Hybrid with 2H-Hexagonal Perovskite Structure

In this work, we focus on [(CH3)2NH2]PbI3, a member of the [AmineH]PbI3 series of hybrid organic-inorganic compounds, reporting a very easy mechanosynthesis route for its preparation at room temperature. We report that this [(CH3)2NH2]PbI3 compound with 2H-perovskite structure experiences a first-order transition at ≈250 K from hexagonal symmetry P63/mmc (HT phase) to monoclinic symmetry P21/c (LT phase), which involves two cooperative processes: an off-center shift of the Pb2+ cations and an order-disorder process of the N atoms of the DMA cations. Very interestingly, this compound shows a dielectric anomaly associated with the structural phase transition. Additionally, this compound displays very large values of the dielectric constant at room temperature because of the appearance of a certain conductivity and the activation of extrinsic contributions, as demonstrated by impedance spectroscopy. The large optical band gap displayed by this material (Eg = 2.59 eV) rules out the possibility that the observed conductivity can be electronic and points to ionic conductivity, as confirmed by density functional theory calculations that indicate that the lowest activation energy of 0.68 eV corresponds to the iodine anions, and suggests the most favorable diffusion paths for these anions. The obtained results thus indicate that [(CH3)2NH2]PbI3 is an electronic insulator and an ionic conductor, where the electronic conductivity is disfavored because of the low dimensionality of the [(CH3)2NH2]PbI3 structure.

Synthesis of a two-dimensional organic-inorganic bismuth iodide metalate through: In situ formation of iminium cations

(Me2CNMe2)Bi2I7 represents a new layered organic-inorganic iodido bismuthate. It displays an unprecedented anion topology, a low band gap and good stability. Advanced electronic structure analysis finds the I?I interactions to be decisive for the compound's structural and electronic properties.

SUBSTITUTION OF THE ANION IN AMMONIUM AND PHOSPHONIUM CHLORIDES BY THE ACTION OF ELECTROPHILIC AGENTS

N,N-Dialkylmethaniminium iodides were obtained by the reactions of N,N-dialkylmethaniminium chlorides with methyl iodide.The reactions of ammonium and phosphonium chlorides with triethyloxonium tetrafluoroborate, dimethyl sulfate, methyl tosylate, and methyl iodide take place with substitution of the chloride ion by the BF4-, CH3SO3O-, p-CH3C6H4SO3- or I- ions.Substitution of the chloride ion of phosphonium salts by the iodide ion can be realized by the action of trimethyliodosilane.

The Mechanism of Photolysis of Some Benzyltrimethylammonium Salts in Water and in Alcohols

Photolysis of a range of benzyltrimethylammonium and 3,5-dimethoxybenzyltimethylammonium salts in water or methanol at 253.7 nm gave typically benzyl alcohols (or benzyl methyl ethers), toluenes, bibenzyls and isomers, and di- and tri-methylammonium salts.By detailed sensitisation and quenching experiments it was established that, in the photolysis of benzyltrimethylammonium bromide in aqueous t-butyl alcohol, benzyl t-butyl ether, benzyl alcohol, and some toluene were produced by a singlet pathway and bibenzyl by a triplet pathway.A general mechanistic scheme for all the photolyses studied is thus suggested.
