Title: Closo-Boranes: Unique Structural Elements for Functional Materials

Abstract: closo-Boranes are inorganic 3-D sigma aromatic compounds with steric and electronic properties attractive for designing multifunctional materials. Earlier work demonstrated that 10- and 12-vertex p-carboranes are suitable building blocks for liquid crystals. Anionic closo-carbaborates have been used to design highly polar materials for LCD applications and ionic self-organizing electrolytes for battery applications. The high-lying HOMO of the decaborate dianion [closo-B 10 H 10 ] 2- has been exploited in the design of materials exhibiting photo-induced intra- and inter-molecular charge transfer processes. The synthesis of these new materials has required the development of new
functionalization methods. For example, phenyliodination activates B-H bonds towards
highly regioselective nucleophilic substitution.
