Opal-like Multicolor Appearance of Self-Assembled Photonic Array
Molecular self-assembly
of short peptide building blocks leads to the formation of various
material architectures that may possess unique physical properties.
Recent studies had confirmed the key role of biaromaticity in peptide
self-assembly, with the diphenylalanine (FF) structural family as
an archetypal model. Another significant direction in the molecular
engineering of peptide building blocks is the use of fluorenylmethoxycarbonyl
(Fmoc) modification, which promotes the assembly process and may result
in nanostructures with distinctive features and macroscopic hydrogel
with supramolecular features and nanoscale order. Here, we explored
the self-assembly of the protected, noncoded fluorenylmethoxycarbonyl-β,β-diphenyl-Ala-OH
(Fmoc-Dip) amino acid. This process results in the formation of elongated
needle-like crystals with notable aromatic continuity. By altering
the assembly conditions, arrays of spherical particles were formed
that exhibit strong light scattering. These arrays display vivid coloration,
strongly resembling the appearance of opal gemstones. However, unlike
the Rayleigh scattering effect produced by the arrangement of opal,
the described optical phenomenon is attributed to Mie scattering.
Moreover, by controlling the solution evaporation rate, i.e., the
assembly kinetics, we were able to manipulate the resulting coloration.
This work demonstrates a bottom-up approach, utilizing self-assembly
of a protected amino acid minimal building block, to create arrays
of organic, light-scattering colorful surfaces
