Some new organic-inorganic hybrid semiconductors based on metal halide units: Structural, optical and related properties

The structural, optical and related properties of organic-inorganic hybrid semiconductors based on the organic molecules (cations) CH3NH3, H3N(CH2)(6) NH3, C5H5CH2NH3, CH3C6H4CH2NH3, CH3OC6H4CH2 CH2NH3, (H2N)(2)CS(CH2)(4)SC(NH 2)(2), H3NCH2CH2OCH2CH2OCH2CH2NH3, C6H5CH2CH2SC(NH2)(2), C10H21SC (NH2)(2), O2NC6H4CH2SC(NH2)(2), 1-naphthylmethylammonium C10H7CH2NH3, 9-anthrylmethy lammonium C14H9CH2NH3 and 1-pyrenylmethylammonium C16H9CH2NH3 and the inorg anic units MXn (anions) (M = Bi,Sb,Sn, Pb, Cu, Ag; X = I, Sr, CI) are descr ibed. There is evidence that the position, intensity and shape of the excit onic bands depend on the order/disorder of the inorganic component and oh t he electronic interaction between organic and inorganic components.
