  • Patent number: 8598151
    Abstract: The present invention relates to solid solution inducing layer for the preparation of weak epitaxial films of non-planar phthalocyanine and the thin film of non-planar phthalocyanine generated from the weak epitaxial growth on the solid solution inducing layer and organic thin film transistor based on the weak rpitaxy growth thin film of non-planar phthalocyanine. The solid solution inducing layer is prepared at certain substrate temperature by vapor co-deposition of any two inducing layer molecules presented by Formula I and Formula II. The solid solution inducing layer has uniformed structure, of which the lattice parameter and electronic structure can be controlled by adjusting the component proportion, the solid solution inducing layer can epitaxially grow a high quality thin film of non-planar phthalocyanine and fabricate high performance transistor device based on such epitaxial thin film.

  • Publication number: 20110152541
    Abstract: The present invention relates to inducing layer materials for the preparation of weak epitaxial films of non-planar metal phthalocyanine. The characteristics of the inducing layer materials lies in that the said inducing layer materials replace benzene rings of sexiphenyl by conjugated aromatic group and to replace the hydrogen atoms of benzene rings at the two ends of sexiphenyl by fluorine atoms, thus the regulation of molecular interaction is finally realized by changing the size or the linearity degree of the conjugated aromatic groups, as well as by changing the polarity of the benzene ring at the two ends, consequently, the cell parameters of (001) crystal face of the new materials are different from that of sexiphenyl and to achieve a effect of inducing the weak epitaxy growth of non-planar metal-phthalocyanine.

  • Patent number: 7057009
    Abstract: Photonic materials include light-emitting organic oligomer compositions that include at least one light-emitting oligomer. The oligomer compositions include oligofluorenes having chiral and/or achiral pendants. The oligomer compositions also include spiro-linked oligofluorenes and fully spiro-configured terfluorenes. Methods for syntheisizing light-emitting organic oligomer compositions include preparing fluorene-based oligomers by convergent/divergent synthesis.

  • Patent number: 7037599
    Abstract: An OLED device comprising a substrate, an anode electrode and a cathode electrode, a uniaxial alignment layer disposed between the anode electrode and the cathode electrode, a light-emitting layer disposed over the uniaxial alignment layer and capable of producing polarized light, and a carrier confinement layer disposed over the light emitting layer and wherein the carrier confinement layer blocks either holes, electrons, or excitons. The light-emitting layer includes an oligomeric fluorene or a mixture of oligomeric fluorenes.
