The study of the interaction between DNA and small molecules such as drugs is one of the current general interest and importance. In this paper, the electrochemical investigation of the interaction between some flavonoids such as rutin, quercetin, and hesperidin with dsDNA on the surface of Supramolecular Ionic Liquid grafted on the Graphene Oxide Modified Glassy Carbon Electrode (</s...
متن کاملChiromers: conformation-driven mirror-image supramolecular chirality isomerism identified in a new class of helical rosette nanotubes.
Rosette nanotubes are biologically inspired nanostructures, formed through the hierarchical organization of a hybrid DNA base analogue (G∧C), which features hydrogen-bonding arrays of guanine and cytosine. Several twin-G∧C motifs functionalized with chiral moieties, which undergo a self-assembly process under methanolic and aqueous conditions to produce helical rosette nanotubes (RNTs), were sy...
متن کاملSpatiotemporal control and superselectivity in supramolecular polymers using multivalency.
Multivalency has an important but poorly understood role in molecular self-organization. We present the noncovalent synthesis of a multicomponent supramolecular polymer in which chemically distinct monomers spontaneously coassemble into a dynamic, functional structure. We show that a multivalent recruiter is able to bind selectively to one subset of monomers (receptors) and trigger their cluste...
متن کاملChiral Solvation Induced Supramolecular Chiral Assembly of Achiral Polymers
To date, liquid crystal chirality, mechanophysical chirality, circularly polarized photon chirality, gelation and chiral solvation are all feasible candidates to generate optically active polymers and supramolecular chirality when employing achiral molecules as start‐ ing substances. Among this, chiral‐solvation‐induced chirality is one of the dominant methods for construction of chirality from...
متن کاملSupramolecular polymerization from polypeptide-grafted comb polymers.
The helical and tubular structures self-assembled from proteins have inspired scientists to design synthetic building blocks that can be "polymerized" into supramolecular polymers through coordinated noncovalent interactions. However, cooperative supramolecular polymerization from large, synthetic macromolecules remains a challenge because of the difficulty of controlling the structure and inte...
