Template and Guest Effects on the Self-Assembly of a Neutral and Homochiral Helix This research was supported by the National Science Foundation (CHE-9818472) and the Alexander von Humboldt Foundation through a Feodor Lynen Fellowship for F.M.T.

Abstract

Coordination-driven assembly based on manganese(II) centers and flexible 1,3-bis(4-pyridyl)propane leads to the solid-state formation of electronically neutral, self-templated homochiral helices, closed ring structures, and racemic mixtures of helices depending upon the presence or absence of guests such as benzene and 1,2-diphenylethane.
