Summary of "Chirality Controlled Self-Assembly of Amphiphilic Dibenzo6helicenes into Langmuir-Blodgett Thin Films."

Racemic and highly enantioenriched 3-methoxycarbonyl, 3-carboxy and 3-hydroxymethyl derivatives of dibenzo[6]helicene were prepared. The Langmuir layers of these helicenes were formed at the air-water interface and transferred onto solid substrates to afford Langmuir-Blodgett films, which were then studied by ambient atomic force microscopy and (chir)optical spectroscopy. Significant differences were found in the behaviour of the Langmuir layers as well as in the morphology, UV-Vis, ECD and fluorescence spectra of the Langmuir-Blodgett thin films depending on the molecular chirality and nature of the polar group. The experimental results were supported by molecular dynamics simulations.
