Abstract

Enantiomeric self-recognition is triggered by addition of [Pd(ONO2)(en)] (2; en=1,2-ethylenediamine) to a solution of (±)-1 in water, a process that results in a 2:2 aggregate (12⋅22 and (ent-1)2⋅22) of well-defined geometry. The use of analytical ultracentrifugation as a tool for the elucidation of molecular weight and stoichiometry in synthetic self-assembly studies is highlighted.
