Abstract

We have used x-ray diffraction and differential scanning calorimetry to establish the phase diagram, liquid crystalline structure, and crystalline structure of a series of hexa-n-alkylthiotriphenylenes. At least nine crystal phases are observed. The helical pitch seen in the helical phase is incommensurate with the molecular spacing when measured in single-orientation strands, while commensurate in powder samples.
