RETRACTED: Electroactive peptide-based supramolecular polymers

Abstract

The electroactivity as a supramolecular feature of intelligently designed self-assembled systems stimulates a wide interest in development of new stimuli-responsive biomaterials. A diverse set of nanostructures are fabricated through programmed self-assembly of molecules for functional materials. Electroactive groups are conjugated as a functional moiety for organic semiconductor applications. In this review, we present recent examples of self-assembling peptide molecules and electroactive units for supramolecular functional electronic ​and optical materials with potential biomedical and bioelectronics applications.

Hierarchical self-assembly of aromatic peptide conjugates into supramolecular polymers: it takes two to tango

“…181,183 The ability to self-organize aromatics into chiral aggregates may also open applications in the field of organic electronic. 184 In this case, the group of Frauenrath combined peptide with polymer side-chains to organize perylene bisimide, quaterthiophene and other chromophores into chiral nanowires. [185][186][187] Figure 12.…”

Peptide-Based Low Molecular Weight Photosensitive Supramolecular Gelators

“…On top of that, the system is free from waste generation/chemical contaminants hence closed systems can be stimulated without introducing any foreign chemicals, and finally, the light can be conveniently switched on and off with specific wavelengths and tunable intensities to modulate and program supramolecular gelation [ 18 , 77 , 79 ]. Considering the utmost advantages of peptides and light, in recent years, a variety of photo-responsive moieties has been incorporated into the peptides to design photo-responsive gelators which can display switchable, smart, and emergent features [ 15 , 80 , 81 , 82 , 83 , 84 ].…”

Single-atom substitution enables supramolecular diversity from dipeptide building blocks

“…1 Thanks to the great chemical diversity of natural and non-canonical amino acids, 2 it is possible to tune the physico-chemical properties of the final product, and this is an attractive feature for different applications spanning from innovative solutions in medicine 3–6 to energy 7,8 and bioelectronics. 9–11 To enable translation into the market, it is key to design systems with low-cost and easy scale-up. For this reason, the minimal building blocks, i.e.…”
