A series of nonmesogenic N-acylated derivatives (2) of 1,10-diaza-4,7,13,16-tetrathiacyclooctadecane (1) affords stable cationic complexes upon reaction with [Cu(MeCN)4][PF6].

Abstract
A series of nonmesogenic N-acylated derivatives (2) of 1,10-diaza-4,7,13,16-tetrathiacyclooctadecane (1) affords stable cationic complexes upon reaction with [Cu(MeCN)4][PF6]. The products [Cu(2)] [PF6] show thermotropic mesomorphism as a result of copper(I) complexation. Optical microscopy, calorimetry, and low-resolution powder X-ray diffraction were used to characterize the liquid-crystalline order. The presence in all complexes of a single mesophase with a lamellar structure is proposed and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
