Ke. Treacher et al., STABLE GLASS-FORMATION BY A HEXAGONAL ORDERED COLUMNAR MESOPHASE OF ALOW MOLAR-MASS PHTHALOCYANINE DERIVATIVE, Liquid crystals, 19(6), 1995, pp. 887-889
The synthesis of a novel phthalocyanine mesogen, containing four flexi
ble side chains terminated with a bulky trityl moiety, is described. T
his compound forms a well defined anisotropic glass, indefinitely stab
le at room temperature, in which the hexagonal ordered structure of it
s columnar mesophase is preserved. Such a glassy state should be usefu
l for anisotropic conductivity studies.
