N2 - The present work reports on experimental structures, optoelectronic, and luminescence properties of the series of low-dimensional hybrid organic-inorganic (1,5-Pentanediamine)PbX4 (X=Cl, Br, I) perovskites. Single-crystal XRD data revealed that the chloride and bromide compounds form quasi 2D perovskite-like structures, whereas the iodide is quasi 1D compound. In accordance with experiment, DFT modeling predicts that the chloride and bromide are direct bandgap semiconductors. In contrast, the iodide is an indirect bandgap semiconductor. Experimentally and theoretically established bandgaps widths of the perovskites follow the same trend. Finally, luminescent properties of the perovskites were investigated. The study shows that the halogen anionsdetermine the degree of disorder of the perovskite crystal lattices and degree of distortion of PbX6 octahedra therein. Both structural phenomena affect dimensionality, optoelectronic, and luminescent properties of the studied perovskites.
