“…The decrease in intrinsic viscosity as a function of intramolecular CL has been described several times in the literature and, as shown in Table , we also observe this expected reduction. Yet, direct analysis of the effect of intramolecular collapse on the solution rheology behavior, that is, viscosity, is rare.…”

The conformation of a polymer in a solvent is typically defined by the solvent quality, which is a consequence of the solvent and macromolecule's chemistry. Yet, additional factors can affect the polymer conformation, such as non-covalent interactions to surfaces or other macromolecules, affecting the amount of polymer-solvent interactions. Herein, chemically folded polymers with protein-like architectures are studied and compared to their unfolded linear precursor in good solvents using rheology measurements. The current research reveals that permanent folding by intramolecular chemical cross-linking limits the chain mobility and therefore causes a reduction in polymer-solvent interactions, making a good solvent become theta. This change not only affects the "solvent quality" but also leads to a change in particle-particle interactions as a function of concentration. These findings provide crucial insight into the effects of intramolecular cross-links on macromolecule solubility and self-assembly, which are critical for mimicking structurally similar biological materials.

“…To our knowledge, the intramolecular cross-linking of linear single polymer chains was first reported in 1962 by Kuhn and Balmer . The topic was revisited in the late 1960s by Rossi et al , and again both theoretically and experimentally by various researchers throughout the 1980s , and 1990s. − The advent of controlled radical polymerization techniques and the development of efficient postpolymerization modification reactions provided a refreshed interest in the topic at the turn of the century. There are currently several research groups studying what are currently referred to as single-chain nanoparticles (SCNP).…”

With the increasing appeal of nanotechnology, there is a demand for development of synthetic techniques for the fabrication of nanosized objects that allow for precise size control and tailored functionalization. To this end, the collapse or folding of single polymer chains into architecturally defined nanostructures is a rapidly growing research topic in polymer science. Many synthetic approaches have been developed for the formation of single-chain nanoparticles (SCNP), and a variety of characterization methods and computational efforts have been utilized to detail their formation and probe their morphological characteristics. Interest in this field continues to grow partially due to the variety of potential applications of SCNP including catalysis, sensors, nanoreactors, and nanomedicine. While numerous developments have been made, the field is continuing to evolve, and there are still many unanswered questions regarding synthesis and characterization of SCNP. This Perspective serves to identify recent accomplishments in the synthesis and characterization of SCNP while distinguishing areas that are in need of advancement and innovation to move forward. This includes exploring more complex synthetic strategies, obtaining folding control, employing nanoparticle functionalization, developing scalable methods, investigating hierarchical self-assembly of SCNP, and exploiting unique characterization techniques and in-depth simulations.

“…The original idea of collapsing a polymer chain with chemical bonds was proposed and studied theoretically by Kuhn in 1956, who also fulfilled the first experimental example in 1962 . This polymer architecture became important as a synthetic approach to produce tiny organic nanoparticles (from 1.5 to 20 nm) that could not be obtained by emulsion polymerizations. − The effect of cross-link density on properties of the individual particles such as shape, , size, − rigidity, ,, and intrinsic viscosity ,, have been largely studied. We recently published a molecular dynamics study of the thermomechanical properties of individual SCPNs as a function of cross-link density .…”

Mechanical and Thermomechanical Characterization of Glassy Thermoplastics with Intrachain Cross-Links

The mechanical properties of an amorphous polymer are a consequence of the inter- and intramolecular interactions which are typically similar. Yet, polymers can be made with covalent intramolecular cross-links, leading to stronger intramolecular interactions. Here, a study on the effect of this intramolecular cross-linking on the mechanical properties of a glassy polymer is shown. A linear poly(methyl methacrylate) with defined size was cross-linked at different ratios and assembled into solid samples by solvent casting. Mechanical testing indicates that intramolecular cross-linking does not affect the mechanical properties at the elastic region but does influence these properties at the plastic region. Interestingly, intramolecular cross-linking leads to different effects than “regular” interchain cross-linking. The results are consistent with a reduction in chain entanglement, reducing toughness and to a lesser extent strength.
