Abstract
Two homologous series of thioether-linked liquid crystal dimers with oppositely directed esters,<italic>viz.</italic>CBCOO<italic>n</italic>SCB and CBOCO<italic>n</italic>SCB, exhibit largely different helical pitches in the N<sub>TB</sub>phase, which are ascribed to their molecular bend or biaxiality.
