Abstract:
The variables which control the degree of molecular ordering of CuPc(OC₂OBz)₈ and H₂Pc(OC₂OBz)₈ within Langmuir-Blodgett (LB) thin films were identified and optimized. Stabilizing the Langmuir film, lowering the subphase temperature, transferring to phenyl terminated substrates, and annealing lead to enhanced ordering. Infrared data confirms increased anisotrophy (dichroic ratio, R-4.6) and order (order parameter, S₂-6.5) within these films, and predicts a tilted elliptical orientation of the molecules. Small angle X-ray scattering data and atomic force microscopy images correlate, giving a column-to-column spacing of ca. 27Å and ca. 29Å, respectively. Ordered LB thin films have charge transport mobilities of ca. 1x10⁻⁴cm²V⁻¹s⁻¹ that may increase with ClO⁻₄ anion insertion. The degree of achieved ordering leads to further investigations into the applicability of LB thin films of CuPc(OC₂OBz)₈ and H₂Pc(OC₂OBz)₈ in molecular electronic devices.
