Abstract
A novel dipolar metallomesogen, the 2,3,9,10,16,17,23,24-octakis(n-octadecylthio)phthalo- cyanatooxovanadium(IV) complex was synthesized and its phase transition behaviour investi- gated. This complex showed a Col h mesophase between the melting and clearing points, 56 and 295 C, respectively. This is the first phthalocyanine metallomesogen possessing a dipolar V=O bond and it shows a relatively low clearing temperature which is attractive for investigation of physical and/or chemical properties related to the dipolar part.
