Molecular analogs of the hemihelix: A computational study of chain molecules containing left- and right-handed helices

Research output: Contribution to journalArticle

Abstract

Using density functional theory (DFT) we design two novel chain molecules containing a left-handed (thia)helicene unit connected to a right-handed (thia)helicene unit via a phosphorousphosphorous (PP) bond. These chains represent the molecular analogs of the novel hemihelix structure recently discovered by a group of Harvard University scientists. The HOMO and LUMO levels of the heterochiral chains, termed hemihelicenes, are localized on the left- and right-handed blocks, respectively. In contrast, the frontier orbitals of the chains containing homochiral (thia)helicenes connected by a PP bond are delocalized all over the chain.
