✦ Synopsis

Dedicated to Dr. G¸nther Seybold on the occasion of his 60th birthday

Functional liquid crystals (LCs) with intrinsic luminescence properties are of great interest in the development of new organic materials, such as anisotropic light emitters, organic lasers, photoconductors, and in LC display technology. [1±3] In contrast to dissolving a fluorescent dye in a LC matrix, fluorescent LCs are thought not only to overcome miscibility and stability problems but also to exhibit novel enhanced optoelectronic properties. To date, only a few examples have been reported such as triphenylenes, [3a±d] benzopyrenes, [3e] hexacatenar compounds, [1a] and perylenes, but the field is IR (KBr):
