Single Component-Uncomplicated Self-Assembly: Conformational Modulation to Regulate Chirality Transformation in Perylene Bisimide Superhelical Assemblies in Aqueous Media.

The progression of supramolecular chirality in synthetic helical assemblies relates directly with the structure of building block, consequently, the generation of right- and left-handed helical assemblies from single component system is highly challenging. Herein, we demonstrate the coupling of designed PBI-Ind buildin...

Dipeptide heterochirality directs global chirality and mesoscale morphology during supramolecular co-assembly.

HYPOTHESIS The origin of biological homochirality and the principles governing heterochiral molecular interactions remain poorly understood. In self-assembling chiral systems, a linear CD-ee relationship generally indicates self-sorting driven by unfavorable heterochiral interactions, whereas nonlinear CD-ee dependence...

Dynamic Supramolecular Helicity in a Multi-Aluminum Porphyrin Catalyst Enables Stereocontrolled Synthesis of Ultrahigh-Molecular-Weight Isotactic Poly(propylene oxide).

Isotactic poly(propylene oxide) (iPPO) is a robust polyether with photodegradability. However, its stereoselective synthesis from racemic propylene oxide (rac-PO) remains dominated by preconfigured axially chiral cobalt/chromium bimetallic catalysts. Here, we report an ion pair-assisted dynamic helical organization str...

Water Helicity-Modulated Hierarchical Inverse Chirality Transfer in Supramolecular Assembly.

Water helicity is ubiquitous in biological architectures (e.g., proteins and enzymes) and plays a crucial role in hierarchical chirality transfer. However, achieving water helicity-modulated hierarchical inverse chirality transfer (e.g., molecular chirality to water helicity and ultimately to nanoscale chirality opposi...

Polygonal assembly of atomically precise Au25 superatoms through mixed-ligand shell engineering.

Atomically precise metal nanoclusters have emerged as a distinct class of superatomic building blocks with unique electronic structures. Although their organization into higher-order architectures is expected to generate emergent collective properties, rational control over assembly morphology while preserving atomic p...

Self-Assembly of a Chiral Pyrene-Bifuran-Imide Into Helical and Spherical Nanostructures.

We report the solvent-dependent self-assembly of 1-Py2, a novel bifuran-imide building block functionalized with terminal pyrene units and an enantiopure, alanine-derived chiral side chain. In pure tetrahydrofuran, 1-Py2 exists as a monomer with no electronic circular dichroism (ECD) signal. Increasing the water conten...
