Perylo[1,12-<i>b</i>,<i>c</i>,<i>d</i>] thiophene tetraesters exhibiting wide-range
hexagonal columnar
phase have been synthesized. These compounds also exhibit good homeotropic
alignment in the liquid-crystalline phase which is very important
for the device fabrication. These compounds showed sky-blue luminescence
in solution under the long-wavelength UV light. With high solubility
and high quantum yield these compounds can serve as standards to measure
quantum yields of unknown samples. This new class of materials is
promising, considering the emissive nature and stabilization of hexagonal
columnar mesophase over a wide thermal range and ease of synthesis.
