A novel organic-inorganic hybrid material, (NH3C6H4OC6H4NH3)PbI4 with a perovskite structure, was synthesized and characterized by elemental analysis, UV-Vis, X-ray diffraction (XRD) and TEM techniques. XRD patterns from its powder showed that the hybrid material was well-ordered and in layered frame. Electric measurements performed on the spin-coated films from the organic-inorganic hybrid material have demonstrated a room-temperature electron mobility as high as 0.065 cm2•V-1•s-1, which is a promising material for photoelectric devices.

Key words: organic-inorganic hybrid, perovskite, mobility
