摘要

Composite materials of quantum particles (Q-particles) arranged in layers within crystalline powders of #pi#-conjugated, rodlike dicarboxylic acids are reported. The synthesis of the composites, either as three-dimensional crystals or as thin films at the air-water interface, comprises a tow-step process: 1) The preparation of the Cd salts 6(Cd), 8(Cd) or Pb salts 6(Pb), 8(Pb) of the oligo(p-phenyleneethynylene)dicarboxylic acis 6(H), 8(H), in which the metal ions are aranged in ribbons and are separated by the long axis of the organic moleucles, as demonstrated by X-ray pwoder diffraction analysis of the solids and grazing incidence X-ray diffraction analysis of the films on water. 2) Topotactic solid/gas reaction of these salts with H_2S to convert the metal ions into Q-particles of CdS or pbS embedded in the organic matrix tht consists of the acids 6(H) and 8(H). These hybrid materials have been characterized by X-ray photoelectron spectroscopy and transmission electron microscopy.
