A structurally new type of core-to-core dimers with a top-to-bottom linkage between the central cores of bent molecules is presented. The structure of bent-core molecules was modified by changing the length of the spacer between the central cores and terminal chains, by changing the type of linkage groups in bent-core arms and by variation of the terminal chain polarity - introducing polyfluoroalkyl and oligosiloxane units. Additionally, the outer phenyl ring was substituted with three alkyl chains to mimic a polycatenar system. For all compounds the mesophase behaviour and structural parameters were established.
