Development of Covalent Triazine Frameworks as Heterogeneous Catalytic Supports [PDF]

Polymers, 2019
Covalent triazine frameworks (CTFs) are established as an emerging class of porous organic polymers with remarkable features such as large surface area and permanent porosity, high thermal and chemical stability, and convenient functionalization that promotes great potential in heterogeneous catalysis.

Covalent Triazine Frameworks via a Low‐Temperature Polycondensation Approach [PDF]

Angewandte Chemie - International Edition, 2017
AbstractCovalent triazine frameworks (CTFs) are normally synthesized by ionothermal methods. The harsh synthetic conditions and associated limited structural diversity do not benefit for further development and practical large‐scale synthesis of CTFs. Herein we report a new strategy to construct CTFs (CTF‐HUSTs) via a polycondensation approach, which ...

Advances in the Synthesis of Covalent Triazine Frameworks. [PDF]

ACS Omega, 2023
Covalent triazine frameworks (CTFs) are a class of organic polymer materials constructed by aromatic 1,3,5-triazine rings with planar π-conjugation properties. CTFs are highly stable and porous with N atoms in the frameworks, possessing semiconductive properties; thus they are widely used in gas adsorption and separation as well as catalysis.

Rigid Nanoporous Urea-Based Covalent Triazine Frameworks for C2/C1 and CO₂/CH₄ Gas Separation [PDF]

Molecules, 2021
C2/C1 hydrocarbon separation is an important industrial process that relies on energy-intensive cryogenic distillation methods. The use of porous adsorbents to selectively separate these gases is a viable alternative.

Topological Study on Triazine-Based Covalent-Organic Frameworks

Symmetry, 2022
Most of the research has evidenced that there is a strong natural correlation among the chemical properties of molecular structures. This study analyses supramolecular chemistry and investigates topological indices of supramolecular structures called triazine-based covalent-organic frameworks.

Room-temperature methanol synthesis via CO2 hydrogenation catalyzed by cooperative molybdenum centres in covalent triazine frameworks [PDF]

Nature Communications
Selective hydrogenation of CO2 into methanol offers an ideal route for the utilization of greenhouse gas, but it remains a great challenge to be carried out under mild conditions due to the intrinsic chemical stability of CO2.
