Macrocyclic metallomesogens: thermotropic double-chained silver amphiphiles
Abstract
Mesomorphic [Ag(2)][TfO](TfO = CF3SO3) and [Ag(2)][TsO](TsO =p-CH3C6H4SO3) have been prepared by silver complexation of the novel N,N′-bis(hexadecanoyl)-1,10-diaza-4,7,13,16-tetrathiacyclooctadecane, 2. The phase behaviour of the silver complexes is described and a lamellar mesophase is proposed for [Ag(2)][TfO] by means of X-ray evidence.
