Incorporation of narcissistic self-sorting supramolecular interactions for the spontaneous fabrication of multiple-color solid-state materials for OLED applications

Abstract

A hat trick makes vesicles self-sort into their color families!

100th Anniversary of Macromolecular Science Viewpoint: Engineering Supramolecular Materials for Responsive Applications—Design and Functionality

“…As the field of supramolecular self-assembly expands, more complex materials will be required to accommodate evolving technological needs. Some areas that have already benefited from concepts derived from supramolecular polymeric assembly aside from those discussed previously in detail, include organic light emitting diodes (OLEDs) and photovoltaic materials. ,, In such cases, the ability of supramolecules to form well-ordered nanostructures can be used to encourage sorting of molecular arrays, enhance toughness and tear resistance, and promote polymer blend miscibility which can expand applications of these materials. Enhanced understanding of how the organization of these supramolecular arrays is dictated by their environment will facilitate innovation of these next-generation materials.…”

Self-sorting assembly of artificial building blocks

“…Introducing steric mismatch or resistance was also fairly easy in supramolecular assemblies of small molecules, including those bearing π–π stacking 119 or hydrogen bonds. 120,121 In these systems, mismatch was obviously enhanced so that self-sorting assemblies could be readily realized.…”

Narcissistic Self-Sorting of Amphiphilic Collagen-Inspired Peptides in Supramolecular Vesicular Assembly

“…Self-sorting is a rampant molecular event in living organisms, such as in DNA double helix formation and quaternary structuring of proteins, where multiple biomolecules are assembled into specific ordered structures such as heterocomplexes (social self-sorting) or homocomplexes (narcissistic self-sorting). , In synthetic supramolecular systems, such self-sorting systems have also been fabricated based on molecular recognition events such as hydrogen bonding, ,, anion–ligand coordination, steric suitability or chirality, , and kinetic control of the self-assembly process. ,, These events have also been observed at a wide range of levels, from the molecular scale to the micro-scale, and are useful for understanding complex self-assembly pathways in natural biological systems. Despite these successful advances, the creation of a novel self-sorting system from multiple peptides with conformational similarity remains highly challenging due to difficulties in discriminating among the components, both during molecular complexing and further self-assembly processes.…”
