The synthesis of an ionic quaterrylenebis(dicarboximide) 1a, a long-wavelength absorbing mesogen, is described. When compared with its analogue 2a, an ionic perylenebis(dicarboximide), the aromatic protons of 1a exchange with deuterium of concentrated D2SO4 at a dramatically faster rate. In addition, stronger aggregation in aqueous media was observed for 1a.

We have developed an approach to generate micropatterns of anisotropic organic materials which exploits the self-organization, driven by π-stacking and hydrophobic interactions, of an ionic perylenebis(dicarboximide) 1 in aqueous solutions.

The invention provides materials and methods for making anisotropic solids which may be in the form of films, layers, shaped elements, and other shaped articles. The methods provide anisotropic solids without the need for rolling, rubbing, or stretching to impart orientational alignment of the molecules of the solid. The methods employ organic or organometallic compounds which are soluble orienting molecules. The solvent or solvent system must be sufficiently volatile to be removed without disruption of the molecular orientation. The soluble orienting molecules include those containing one or more hydrophilic and/or ionic groups and the solvent or solvent system can be a polar organic solvent or solvent system or an aqueous solvent or solvent system. The invention also provides novel compounds having quaterrylene, perylene and naphthalene ring systems carrying one or more hydrophilic and/or ionic groups. These novel compounds can exhibit useful absorption and fluorescence properties in solution and in the solid phase and can exhibit useful liquid crystalline properties.

The present invention relates to a lyotropic chromonic liquid crystal composition, a method for manufacturing a lyotropic chromonic liquid crystal coating film and a lyotropic chromonic liquid crystal coating film manufactured thereby. The lyotropic chromonic liquid crystal composition of the present invention includes chromonic liquid crystal compounds and monomers each having opposing acid-base properties. Use of the lyotropic chromonic liquid crystal composition in the formation of optical films leads to improvements in electrical and optical properties such as mechanical strength, an insulating characteristic and a refractive index.
