Significance A fundamental challenge in materials science is to understand the atomic-level structures of nanoarchitectures assembled from synthetic polymers. Here, we report a family of sequence-defined polypeptoids that form free-floating crystalline 2-dimensional nanosheets, in which not only individual polymer chains and their relative orientations, but also atoms in nanosheets were directly observed by cryogenic transmission electron microscopy. These atomic details are inaccessible by…

Importance of the Positively Charged σ-Hole in Crystal Engineering of Halogenated Polypeptoids.
Crystalline nanosheets formed by amphiphilic block copolypeptoids with halogenated phenyl side chains were imaged at the atomic-scale using cryogenic transmission electron microscopy (cryo-TEM). In
Crystallization and self-assembly of shape-complementary sequence-defined peptoids
The universal pairing of complementary nucleobases in DNA found in all life forms has inspired extensive studies on selective molecular recognition between information-rich sequence-defined polymer
Hierarchical Self-Assembly Pathways of Peptoid Helices and Sheets.
TLDR
A new understanding of hierarchical peptoid assembly and principles for the design of peptoid-based nanomaterials are established by identifying a thermodynamically controlled assembly mechanism by which monomers assemble into disordered aggregates that self-order into 1D chiral helical rods then 2D achiral crystalline sheets.
From Distinct Metallopeptoids to Self-Assembled Supramolecular Architectures.
TLDR
It is demonstrated that changing only one non-coordinating side-chain within peptoids - sequence-specific N-substituted glycine oligomers - leads to different supramolecular structures, and the selective recognition abilities of the nano- channels towards glycerol are demonstrated.
Impact of Nanoparticle Size and Surface Chemistry on Peptoid Self-Assembly
Self-assembled organic nanomaterials can be generated by bottom-up assembly pathways where the structure is controlled by the organic sequence and altered using pH, temperature, and solvation. In

Nanoparticle-Mediated Assembly of Peptoid Nanosheets Functionalized with Solid-Binding Proteins: Designing Heterostructures for Hierarchy.
TLDR
This work reports on the synthesis of 3.3-nm-thick thiol-reactive peptoid nanosheets from equimolar mixtures of unmodified and maleimide-derivatized versions of the Nbpe6Nce6 oligomer, and triggers the stacking of these 2D structures into a multilayered material composed of alternating peptoid, protein, and organic layers.
Where Biology and Traditional Polymers Meet: The Potential of Associating Sequence-Defined Polymers for Materials Science
TLDR
This perspective considers the synergistic advantages that can be achieved via tailoring both precise sequence control and attributes of traditional polymers in a single system and examines sequence-defined polymers as key model systems for studying previously unresolvable questions in polymer physics.

Design, Synthesis, Assembly, and Engineering of Peptoid Nanosheets.
TLDR
It is discovered that individual peptoid polymers with a simple sequence of alternating hydrophobic and ionic monomers can self-assemble into highly ordered, free-floating nanosheets, which provide a robust platform for the discovery of new classes of nanOSheets with tunable properties and novel applications.

TLDR
A secondary structure displayed by biomimetic peptoid polymers in which the backbone exhibits the cis conformation and alternating residues display rotational states of opposed (pseudo)chirality is reported.

TLDR
This study demonstrates that when packed into supramolecular lattices or crystals, peptoid polymers prefer to adopt a regular, extended, all-cis secondary structure.

TLDR
This analysis compares polymerizations in (initially) a homogeneous phase with those at interfaces and considers structural aspects of monomers as well as possibly preferred connection modes, and briefly touches upon how the chances for a successful structural analysis of the final product can possibly be increased.
