title: Preparation, mesomorphic properties and behaviour of 4,4'-biphenylenedibenzoates as stationary phases in gas chromatography.
abstract: This paper describes the preparation, mesomorphic properties and behaviour as stationary phases of a series of biphenylenedibenzoates. These compounds exhibit broad mesomorphic ranges with high solid-crystal-liquid-crystal transition temperatures, and give relatively short retention times in the determination of polynuclear aromatic hydrocarbons. The chromatographic selectivity for linear and planar structures is confirmed.
