Methano[10]annulene revisited: extended delocalization through conjugated polymers bearing larger Hückel aromatics

Abstract

A comparative study of conjugated polymers derived from the two 10 pi electron circuits of naphthalene and methano[10]annulene is presented. The annulene pi topology allows for a greater degree of intrapolymer charge delocalization, a key structural parameter for enhancing the performance of organic semiconductors. Molecular design and synthesis based upon unusual aromatic cores will enable facile transport properties that would not ordinarily be realized under the 6 pi electron aromatic paradigm.
