Abstract
The ''in-plane anisotropy'' of a triphenylene derivative in Langmuir-B lodgett (L.B.) films has been investigated. Upon heating, L.B.films ex hibit a reversible phase transition appearing as an abrupt increase fr om a low to a high ''in-plane anisotropy'' corresponding to the format ion of the same hexagonal liquid crystal phase observed in the bulk ma terial at almost the same temperature, with the columnar axis aligned along the dipping direction.
