Abstract
A novel dipolar metallomesogen, the kis(n-octadecylthio)phthalo-cyanat ooxovanadium(IV) complex was synthesized and its phase transition beha viour investigated. This complex showed a Col(h) mesophase between the melting and clearing points, 56 and 295 degrees C, respectively. This is the first phthalocyanine metallomesogen possessing a dipolar V=O b ond and it shows a relatively low clearing temperature which is attrac tive for investigation of physical and/or chemical properties related to the dipolar part.
