Mesogenic cavitands have been prepared for the first time. They form uniaxial disordered columnar mesophases (D-hd). The structure requirements for mesophase formation have been identified: (i) macrocyclic cores with thickness below 5 Angstrom and (ii) four large (3,4,5-tris{[4-(dodecyloxy)benzyl]oxy}benzoyl)oxy groups at the upper rim. The orientation of the molecules within the columns is random, excluding the formation of intracolumnar cavities of molecular dimensions in the mesophase.

Abstract
Mesogenic cavitands have been prepared for the first time. They form uniaxial disordered columnar mesophases (D-hd). The structure requirements for mesophase formation have been identified: (i) macrocyclic cores with thickness below 5 Angstrom and (ii) four large (3,4,5-tris{[4-(dodecyloxy)benzyl]oxy}benzoyl)oxy groups at the upper rim. The orientation of the molecules within the columns is random, excluding the formation of intracolumnar cavities of molecular dimensions in the mesophase.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
