Studies on Liquid Crystals of Phenanthrene Derivatives 2, 7-Dialkoxyphenanthrene

Abstract

2, 7-Dialkoxyphenanthrenes with long alkyl chains have been synthesized by the alkylation of the corresponding hydroquinone. The products show liquid crystallinebehavior when the carbon number of the alkyl groups is 6-14. They are all smectic as judged by DTA and the microscopic observations. The results are shown in Fig. 2 and Table2.
