Anomalous inclusion of chloride ions in ethylenediammonium lead iodide turns 1D non-perovskite into a 2D perovskite structure
In this work, we demonstrate that 1D EDPbli crystals containing face -sharing Pb164- octahedra are synthesized using ethylenediammonium (ED) as an organic cation in hydroiodic acid. However, by the addition of hydrochloric acid to the synthetic solution, 2D [(ED)2Pb14]02 crystals are interestingly constructed without substitution of iodides by chlorides. The importance of chloride ions in the structure has been revealed by employing the single -crystal X-ray diffraction technique. Isolated chlorides, through forming hydrogen bonds with ammonium groups and creating (ED)202z+ templating layers, lessen the interplays between organic cations and inorganic units and consequently lead to the formation of almost undistorted Pb1,2- perovskite layers. The band gaps of the resultant crystals have been determined to be 2.72 eV and 2.30 eV for EDPb14 and [(ED)2Pb14]02, respectively. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) measurements indicate that both compounds are thermally stable up to 250 C without any phase transition.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 50-84-0. HPLC of Formula: C7H4Cl2O2.
