This thesis explores the synthesis and characterization of novel hybrid halide Ruddlesden-Popper compounds, which are derivatives of three-dimensional AMX3 perovskites, where A represents a monovalent cation, M a divalent metal cation, and X a halogen. The focus is on compounds with the general formula (L)2(CH3NH3)n−1PbnI3n+1, where L is a monovalent spacer cation, showcasing a layered crystal structure with perovskite-like layers separated by organic cation spacers. Two specific Ruddlesden-Popper compounds, incorporating a conjugated cation, 2-(4- biphenyl)ethylammonium (BPEA), were synthesized using solvothermal and solvent evaporation techniques.The structural elucidation of these compounds, (BPEA)2PbI4 and (BPEA)2(CH3NH3)Pb2I7, was achieved through X-ray crystallography. The ambient stability of these compounds was confirmed over time using powder X-ray diffraction. The investigation extended to the photoelectronic properties of these compounds, where transient photoconductance was measured by time-resolved microwave conductivity. Band-gap calculations of these two compounds was determined from absorption spectra, resulting in optical properties comparable to those of simpler alkyl ammonium cation-based Ruddlesden-Popper compounds.The comprehensive study presented herein not only advances the understanding of hybrid halide Ruddlesden-Popper compounds but also contributes to the development of materials with potential applications in optoelectronics, highlighting the synthesis methods, structural analysis, and functional characterization as essential tools in the material scientist's toolkit.
