Chiral, smectogenic pendant groups have been covalently attached to cyclic oligosiloxanes by hydrosilylation. These materials and the olefinic compounds from which they were derived exhibit ferroelectric behavior. The mesomorphic range, and in particular

A set of 27- to 39-membered pyridine macrocycles 2 and 3 has been synthesized by Williamson ether synthesis or ringclosing metathesis. The pyridines are 2,6-disubstituted to al-low endo interactions. In addition to the length, also the nature of the aliphatic chain was varied: saturated (2) and unsaturated (3).
