Device-Compatible Chiroptical Surfaces through Self-Assembly of Enantiopure Allenes
Chiroptical methods
have been proven to be superior compared to
their achiral counterparts for the structural elucidation of many
compounds. To expand the use of chiroptical systems to everyday applications,
the development of functional materials exhibiting intense chiroptical
responses is essential. Particularly, tailored and robust interfaces
compatible with standard device operation conditions are required.
Herein, we present the design and synthesis of chiral allenes and
their use for the functionalization of gold surfaces. The self-assembly
results in a monolayer-thin room-temperature-stable upstanding chiral
architecture as ascertained by ellipsometry, X-ray photoelectron spectroscopy,
and near-edge X-ray absorption fine structure. Moreover, these nanostructures
anchored to device-compatible substrates feature intense chiroptical
second harmonic generation. Both straightforward preparation of the
device-compatible interfaces along with their chiroptical nature provide
major prospects for everyday applications
