The phenomenon of quantum confinement in hybrid low-dimensional lead-free perovskite derivatives continues to hinder the development of these materials for electron carrier devices such as next-generation solar cells. Spatial separation of metal-halide octahedra within crystal structures yields materials with greater moisture and photodegradation resistance, but at the expense of desired photophys. properties such as small band gaps. We report the synthesis and characterization of an unexplored isomorphic series of perovskite derivatives consisting of isolated dimeric metal-halide M2X104- (M = In, Sb; X = Cl, Br) anions charge-balanced with halopyridinium cations. Assembly of these species results in a supramol. network via extensive noncovalent interactions and may be described as a pseudo-zero-dimensional arrangement. Despite the low dimensionality, these materials display semiconductive optical band-gap energies owing to the appearance of an intermediate band due to hybridization of metal-halide at. and MOs. Low-temperature luminescence measurements provide evidence of electron delocalization where photoexcited metal/halide electrons are captured by organic cations via energetically accessible π* MOs, separating electron/hole pairs. Natural bonding orbital (NBO) calculations reveal that metal hybridization is more pronounced in compounds containing Sb3+ and can be influenced by noncovalent interactions between anionic and cationic building units.4-Iodopyridine(cas: 15854-87-2HPLC of Formula: 15854-87-2) was used in this study.
4-Iodopyridine(cas: 15854-87-2) is used as a reagent in the synthesis of indazolylamides as glucocorticoid receptor agonists. 4-Iodopyridine is a halogenated heterocycle that is a building block for proteomics research.HPLC of Formula: 15854-87-2
