Impacts of Fluorination at the Ortho‐Position of Carboxy Groups on Tetrakis(biphenyl)ethene‐Based Hydrogen‐Bonded Framework

open access: yesSmall, EarlyView.
This work provides new findings on the effect of fluorination on the substitution of TPE derivatives and the modulation of the structure and fluorescence properties of hydrogen‐bonded organic framework (HOF) of F‐CBPE. ABSTRACT Fluorination of building block molecules is one of the effective engineering approaches to modulate molecular assembly in ...

Heavy‐Metal‐Free Colloidal Quantum Dots for Photocatalysis

open access: yesSmall, EarlyView.
Heavy‐metal‐free colloidal quantum dots provide sustainable photocatalytic platforms by combining tunable band structures, strong light absorption, and programmable surfaces/interfaces. This Review highlights how core/shell engineering, alloying, defect regulation, ligand design, and hybrid‐interface construction direct charge separation and ...

Metal‐Organic Framework‐Templated Deconstruction‐Reconstruction Enables One‐Dimensional to Two‐Dimensional Self‐Assembly of Transition Metal Phosphates for High‐Performance Ammonia Sensing

open access: yesSmall, EarlyView.
One‐dimensional nickel phosphate nanofibres are transformed into two‐dimensional quasi‐nanosheets through a metal‐organic framework‐templated deconstruction‐reconstruction strategy. The hierarchical nanofibre‐assembled architecture provides rich mesoporosity, accessible adsorption sites, and rapid ammonia diffusion, enabling high‐performance QCM ...

Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

open access: yesSmall, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.

Programmable Chirality Transfer: Seeding‐Directed Co‐Assembly of Functional Molecules With Amyloid Frameworks

open access: yesSmall, EarlyView.
Seeding‐directed co‐assembly enables efficient chirality transfer from chiral amyloid scaffold to achiral functional molecules. Controlled assembly pathways result in hierarchical hybrid supramolecular structures showing enhanced induced electronic circular dichroism (IECD) and/or vibrational circular dichroism (IVCD).

Unraveling the effect of topological structures of B/N‐doped conjugated macrocycles on spectral properties: A computational study

open access: yesSmart Molecules, EarlyView.
Herein, we constructed a series of fully B‐doped, fully N‐doped and hybrid B/N‐doped conjugated macrocycles considering three key topological factors. At a fixed ring size, the spectra initially redshift then blueshift with varying B/N ratio, while ring size exhibits negligible impact on spectra.
