Liquid crystals of bowl-like molecules

Seven compounds consisting of a rigid bowl-like core and six flexible side chains were synthesized. Five of them exhibit mesophases. Their mesomorphic properties were studied by differential scanning calorimetry, X-ray diffraction and optical microscopy. The experiments show that bowlic molecules ca...

More Information
Summary:Seven compounds consisting of a rigid bowl-like core and six flexible side chains were synthesized. Five of them exhibit mesophases. Their mesomorphic properties were studied by differential scanning calorimetry, X-ray diffraction and optical microscopy. The experiments show that bowlic molecules can form relatively well ordered columnar mesophases.
