| Organic materials have potential applications as optical and electronic materials, in luminescent devices, and in microelectronic fields. The properties of organic materials and the performance of devices based on these materials are strongly influenced by the molecular order and intermolecular interactions in the solid state. Materials in which the organic molecules are anisotropically (directionally) oriented possess unique direction-dependent properties that are unattainable from materials in which molecules are randomly oriented. Micro-patterned anisotropic organic materials are of particular interest to us because of their potential applications in the microelectronic fields, as holographic films, as viewing angle-dependent optical materials, and in stereoscopic displays. In this paper, we report the synthesis of and studies performed on perylenebis(dicarboximide)s and perylenedicarboximides that self-organize to give chromonic liquid crystals and crystals with anisotropic properties. The liquid crystals and crystals of these compounds exhibit dichroic (direction-dependent) absorption and anisotropic fluorescence emission in the visible light region. Self-organization of these compounds on a micropatterned polymer template led to the formation of anisotropic fluorescent materials in micropatterns. |
