The (E,E)-3,6-bis(2-arylethenyl)-1,2,4,5-tetrazines 8 were prepared in a synthetic sequencve starting with aromatic aldehydes 1 and cinnamic acids 2, respectively (Scheme 1).The rod-like conjugated molecules represent clamitic mesogens as well as extended chromophores.Hence, we investigated the formation of liquid crystals, achieved by the introduction of long flexlible side chains, and the photochemical behaviour that is characterized by the fragmentation of the central ring (Scheme 3).

Four series of biforked or polycatenar mesogens derived from 3,4-dialkoxycinnamic or 3-(3',4'-dialkoxyphenyl)propanoic acids are described.These derivatives exhibit an extremly complex polymorphism including lamellar and columnar mesophases as well as nem
