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 state. The molecular orientation of the discotic oligomesogens on rubbed polyimide layers has been investigated.
