Phase transition studies of the liquid crystal 4-[4-n-hexyloxybenzylidene amino] azobenzene thermal microscopy and DSC

The phase transition temperatures of the liquid crystal 4‐[4‐n‐hexyloxybenzylideneamino]‐azobenzene have been investigated by the thermal microscopy and the Differential Scanning Calorimetric (DSC) studies. These studies confirm that this mesogen exhibits nematic, smectic A and smectic B phases. The...

Zusammenfassung:The phase transition temperatures of the liquid crystal 4‐[4‐n‐hexyloxybenzylideneamino]‐azobenzene have been investigated by the thermal microscopy and the Differential Scanning Calorimetric (DSC) studies. These studies confirm that this mesogen exhibits nematic, smectic A and smectic B phases. The transition enthalpies, transition entropies and also the textures exhibited by the different phases are presented.
