Synthesis, Properties, and Two-Dimensional Adsorption Characteristics of [6]Hexahelicene-7-carboxylic acid

A convergent synthesis of racemic [6]hexahelicene- 7-carboxylic acid by cross-coupling of a bicyclic and a tricyclic component is described. A metal-catalyzed ringclosure is also a fundamental component of the synthetic approach. Scanning tunneling microscopy (STM) measurements of the racemate self-...

Zusammenfassung:A convergent synthesis of racemic [6]hexahelicene- 7-carboxylic acid by cross-coupling of a bicyclic and a tricyclic component is described. A metal-catalyzed ringclosure is also a fundamental component of the synthetic approach. Scanning tunneling microscopy (STM) measurements of the racemate self-assembled on Au(111) at liquid-solid interface revealed the formation of ordered racemic 2D crystals.
