J. Johnstone et al., INVESTIGATING THE ORIENTATIONS OF LANGMUIR-BLODGETT-FILMS OF COPPER TETRA-T-BUTYL PHTHALOCYANINE USING POLARIZED, ULTRA-SOFT XANES SPECTROSCOPY, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 278, 1996, pp. 157-164
Phthalocyanines have long been of special interest as essentially orga
nic molecular conductors with properties that can be modulated by vary
ing the central atoms. Soluble phthalocyanines have recently been deve
loped enabling the production of Langmuir-Blodgett films, of interest
to the electronics industry. Data are presented for the determination
of the orientation of a Langmuir-Blodgett film of copper tetra-t-butyl
phthalocyanine using XANES spectroscopy and showing that the molecule
s in the films are oriented normal to the substrate surface.
