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