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.
