ABSTRACT:
The present invention relates to novel liquid crystalline compounds having the following formula: ##STR1## In the above formula, a is 1 or 2, or R.sub.1 and R.sub.2 may be virtually any chemical groups which will maintain the liquid crystalline properties of the resultant compound. The novel compounds of the present invention contain a biphenylcarboxylate ester moiety so as to define a new class of liquid crystalline compounds. The present invention further includes polymers made from the novel liquid crystalline compounds by attaching the compounds to a polymer backbone such as a polysiloxane backbone. Additionally, the present invention also contemplates methods for using such polymers as stationary phases in the chromatographic analysis of various chemical compounds, such as polycyclic aromatic hydrocarbons (PAH).
