We present a supramolecular templating strategy for inducing chirality in hybrid perovskites via confined crystallization within chiral super spaces-nanoconfined, helically ordered cavities formed by the self-assembly of achiral bent-core molecules with chiral additives. Upon removal of the additives, the resulting porous films retain permanent chirality. Quasi-2D hybrid organic-inorganic perovskites crystallized within these templates exhibit distinct chiroptical activity, including mirror-image circular dichroism and circularly polarized light emitting (CPLE), with CPLE dissymmetry factors reaching up to 1.

Polyoxometalate (POM)-type supramolecular materials have unique structures and hold immense potential for development in the fields of biomedicine, information storage, and electrocatalysis. In this study, (NH) [AlMoOH]·7HO was employed as a polyacid anion template, pentacyclic imidazole molecules served as organic ligands, and the moderate-temperature hydrothermal and natural evaporation methods were used in combination for the design and synthesis of two octamolybdenum-oxo cluster (homopolyacids containing molybdenum-oxygen structures as the main small-molecular structures)-based organic-inorganic hybrid compounds, [(CNH)(CNH)][(-MoOH)] () and {Zn(CNH)}{[(-MoO)(CNH)]}·2HO (). Structural and property characterization revealed that both compounds crystallized in the -1 space group with relatively stable three-dimensional structures under the action of hydrogen bonding.

The selective oxygenation of organic compounds via Baeyer-Villiger (B-V) oxidation is crucial for producing value-added chemicals. Although biomimetic catalysts inspired by Baeyer-Villiger monooxygenase (BVMO) and employing a flavin cofactor have shown promise, their effectiveness has been limited by the difficulty in replicating enzymatic active sites, particularly for producing versatile lactones with low ring strain (e.g.

Removing Aflatoxin B (AFB) from food, particularly edible oil detoxification, is a challenge without losing nutrients and flavor components. In this study, enzyme mimics with high-performance for AFB degradation was developed by drawing inspiration from laccase's structure and catalytic mechanism, which used de novo designed peptides as building blocks to self-assemble into supramolecular catalysts with built-in enzyme-like active sites. To further improve ability, a novel amphiphilic organic-inorganic hybrid nanoflower (EmNF-P) was constructed by using Cu as inorganic component and enzyme mimics as organic component, and surface-modifying with amphipathic polymer.

The rational design of hybrid organic-inorganic rotaxanes is crucial for advancing molecular machines and functional nanomaterials, yet the integration of metal-oxo clusters into interlocked systems remains challenging. Herein, we present a precision synthesis strategy for hybrid rotaxanes combining γ-cyclodextrin (γ-CD) hosts with Anderson-type polyoxometalate (POM)-based guests. This approach utilizes covalent POM modification coupled with strategically anchored organic functionalities to control supramolecular assembly, enabling the construction of -[2]-, [3]-, and [4]rotaxanes with controlled structural variations.
