Synthesis of Boron Cluster-Containing Rod-like Molecules with Mesogenetic Property

Abstract

Several series of esters containing p-carborane rings were synthesized. The series contain ring structures, which are p-carborane, benzene, bicyclo[2.2.2]octane and cyclohexane. These ring structures are linked by ester group. Their mesogenic properties investigated using thermal analysis (DCS) and optical microscopy. These carborane derivatives show nematic phases.
