| Abstract: | To help understand the influence of polarity and length of the terminal alkyl chain of a molecule on the molecular stacking of a liquid crystal and on its mesogenic behaviour, four new aminophenylazo-(4)-p-alkylbenzenes were prepared and one of them was further studied by single crystal structure determination. The molecular stacking based on this crystallographic data was established, and compared with that of two previously reported homologues. The mesogenic behaviour of this series of compounds was also investigated. |
