Abstract

Stereochemical effects during two-dimensional crystallization of bisheptahelicene diastereomers on a Cu(111) surface have been studied with scanning tunnelling microscopy. The (M,M)- and (P,P)-enantiomers crystallize into a monolayer racemate lattice, whereas the (M,P)-diastereomers aggregate into their own monolayer phase.

摘要

采用扫描隧道显微镜研究了双七螺旋二聚体非对映异构体在 Cu(111)表面二维结晶过程中的立体化学效应。(M,M)-和(P,P)-对映异构体结晶形成单层外消旋晶格，而(M,P)-非对映异构体则聚集形成自己的单层相。
