Tuning organic crystal chirality by the molar masses of tailored polymeric additives
Abstract
Hierarchically ordered chiral crystals have attracted intense research efforts but the need of enantiomeric pure building blocks and difficulties in the precise control of chirality transfer poses a barrier to their application. Here, the authors describe a process which allows preferred formation of one enantiomorph from a racemic solution and the specific oriented attachment of this enantiomorph by balancing stereoselective and non stereoselective interactions.
