Controlled Triazine‐Based Covalent Functionalization of Black Phosphorus for Degradable Hybrid Materials

open access: yesSmall, EarlyView.
A scalable triazine‐based covalent functionalization strategy of black phosphorus nanosheets provides controlled P‐N surface chemistry with enhanced grafting density in the presence of a phase‐transfer catalyst. As a representative example, BP‐sulfated polymer conjugates exhibit strong in vitro antiviral activity against enveloped viruses and ...

Modulating In‐Plane Conjugation and Core Polarity in Naphthalimide‐Based Covalent Organic Frameworks Enables Efficient H2O2 Photosynthesis

open access: yesTransformative Chemistry, EarlyView.
In this work, we integrate photoactive naphthalimide unit into highly crystalline donor–acceptor covalent organic frameworks (D–A COFs) and achieve fine‐tuning of the electronic structure of D–A COFs by synergistically modulating the in‐plane conjugation and core polarity.

Rational design and synthesis of covalent triazine frameworks based on novel N-heteroaromatic building blocks for efficient CO2 and H2 capture and storage [PDF]

open access: yes, 2018
Covalent Triazine Frameworks (CTFs), a nitrogen-rich subclass of Porous Organic Polymers (POPs), show large potential in applications including gas adsorption /separation and heterogeneous catalysis due to their distinctive large surface area, low ...

Delipidisation of wool fibres and the subsequent beneficial properties of delipidised wool fibres

open access: yesColoration Technology, EarlyView.
Abstract Wool fibres are complex matrices of proteins and fatty acids/lipids found both internally and externally. 18‐methyleicosanoic acid (18‐MEA) is covalently bound to the surface of the fibre via a thio‐ester link, and is considered one of the most important lipids as it is responsible for the hydrophobic properties of wool fibres.

Rational Design of Transition‐Metal Dual‐Atom Catalysts: Exploiting Neighboring Effects for Efficient CO2 Reduction

open access: yesCarbon Neutralization, Volume 5, Issue 3, May 2026.
A dual‐atom catalyst with adjustable proximity effects is depicted, showing that variations in metal–metal interactions can modulate electronic structure, intermediate adsorption, and reaction pathways. These changes guide product selectivity in CO2 reduction and highlight design principles for efficient, tunable DAC systems.

Highly crystalline covalent triazine frameworks modified separator for lithium metal batteries

open access: yesEnergy Materials
Covalent organic frameworks (COFs) that selectively enable lithium ions transport by their abundant sub-nano or nanosized pores and polar skeleton are considered as emerging coating materials for separators of lithium metal batteries.
