Chirality Transfer from Single Molecules into Self‐Assembled Monolayers

Abstract: Chiralitätstransfer vom Molekül in die zweidimensionale Schicht wurde durch Rastertunnelmikroskopie beobachtet. Die lateral ausgedehnte Händigkeit in homochiralen Heptahelicen‐Schichten auf Oberflächen von Einkristallen (siehe Bild) resultiert aus der Orientierung der jeweils direkt benachbarten Moleküle. Die intermolekularen Wechselwirkungen sind im Wesentlichen abstoßende Kräfte zwischen den starren Helices, wodurch ein direkter Chiralitätstransfer ermöglicht wird.

“…[12] STM was also used to get insights into various aspects of chirality at surfaces, including intermolecular chirality recognition and transfer, [13] two-dimensional separation of enantiomers, [14] and chiral amplification. [15] Here we show that the two distinct enantiomeric states of a chiral single adsorbate can be interconverted by inelastic electron tunneling (IET).…”

“…Insbesondere die Adsorption von [7]Helicen an Cu(111) wurde dazu genutzt, die Prinzipien der Selbstorganisation dieser chiralen Kohlenwasserstoffe zu ergründen. [9] Dabei wurde gezeigt, dass racemisches Heptahelicen Zickzackreihen aus alternierenden P-und M-konfigurierten Molekülen bildet.…”

“…[1] The unique chirality effects in LCs have been studied widely, [2] including the molecular induction mechanism in thermotropic LCs [3] and in a self-assembled twodimensional model system. [4] For LLCs, however, the molecular induction mechanism in the N* phase has been a matter of discussion for more than 20 years. [5][6][7][8][9][10][11] There are two proposed mechanisms: a) a dispersive chiral interaction between dopants in adjacent micelles (the dopant should preferentially be located at the micellar surface), and b) a steric dopant-amphiphile interaction yielding distorted micelles (in this case the solubilization of the chiral dopant within the micelle should be favorable).…”
