In continuation of our work on photo-and electron collision-induced reactions of thi01-l~~ and selenol-esters", 61 we have now synthesized the selenocarboxylic Se-aryl esters (2)-( 5 ) as first examples exhibiting liquid crystal properties. The positions of their carbonyl absorptions are typical for
