- Abstract
The synthesis of chiral triphenylenes 7a, b bearing side chains derived from enantiomerically pure trimethyloctanoate 1a and tetramethyldecanoate 1b from the preen-gland wax of domestic goose was achieved in 3 or 4 steps. Compounds 7a, b were nonmesogenic; however, mixtures of 7a, b with hexakis(octyloxy)triphenylene or hexakis(decyloxy)triphenylene displayed columnar mesophases or soft crystal G phases, as was shown by differential-scanning calorimetry and optical-polarizing microscopy. Circular-dichroism measurements revealed weak associations of 7a, b in solution.
