A photoreactive crystalline quasiracemate
Grove, R.C.; Malehorn, S.H.; Breen, M.E.; Wheeler, K.A. A photoreactive crystalline quasiracemate. Chem. Commun. (Cambridge, U. K.), 2010, 46, 7322-7324.
Rationally designed racemic and quasiracemic sulfonamidecinnamic acids assemble to give hydrogen-bonded dimers with coplanar alignment of neighboring olefins. The quasiracemate phase contains near inversion-related motifs with chemically distinct components forming supramolecular heterodimers that undergo asymmetric photodimerization.
