High strength disclinations induced by hydrogen bond dissociation in the nematic phases of p-alkoxycinnamic acids

Pages 605-608 | Received 01 Sep 2001, Published online: 06 Aug 2010
 

Abstract

Disclinations of high strength (S 1) in the hydrogen bond-induced nematic phases of p-alkoxycinnamic acids are reported. The existence of the disclinations of high strength is ascribed to the partial dissociation and regeneration of the hydrogen bonds in a mesastable equilibrium state around the clearing point and the core of the high strength disclination is an isotropic area.
