2,4-Diamino-6-phenyl-1,3,5-triazines grafted with one or two semiperfluorinated chains at the phenyl substituent have been investigated in binary mixtures with one-chain and two-chain oligo(dimethylsiloxy) terminated 4-alkoxy- and 3,4-dialkoxybenzoic

Calamitic fluorophores are presented possessing either two phenylethylene or phenylacetylene fragments which are connected via an aromatic entity. The new compounds exhibit smectic C and/or nematic liquid crystalline phases. The chromophores show flu

A 2,4-diamino-6-phenyl-1,3,5-triazine carrying a single oligo(ethylene oxide) (EO) chain has been investigated in binary mixtures with two-chain and three-chain semiperfluorinated benzoic acids. Mixtures of the triazine with three equivalents of the

An alkoxyphenyl-substituted melamine derivative has been investigated in binary mixtures with two-chain and three-chain semiperfluorinated benzoic acids. Equimolar mixtures of the melamine with the complementary benzoic acids form discrete hydrogen-b

The alignment behaviour of a nematic‐columnar phase forming discotic liquid crystal was explored on various substrates. The mesogen employed was a new star‐shaped monodisperse oligomesogen characterized by three flat radial pentaalkynylbenzene mo

New star-like oligomers are presented characterized by the chemical linkage of a defined number of disc-shaped multialkynylbenzene moieties via a central linking unit. The compounds exhibit a nematic mesophase which can be quenched into a glassy stat
