Two-Dimensional Hetero- to Homochiral Phase Transition from Dynamic Adsorption of Barbituric Acid Derivatives.

ABSTRACT: Barbituric acid derivative (TDPT) is an achiral molecule, and its adsorption on a surface results in two opposite enantiomerically oriented motifs, namely TDPT-S_p and R_p. Two types of building blocks can be formed; block I is enantiomer-pure and is built up of the same motifs (format S_pS_p or R_pR_p) whereas block II is enantiomer-mixed and composes both motifs (format S_pR_p), respectively. The organization of the building blocks determines the formation of different nanoarchitectures which are investigated using scanning tunneling microscopy at a liquid/HOPG interface. Sophisticated, highly symmetric "nanowaves" are first formed from both building blocks I and II and are heterochiral. The "nanowaves" are m
