A Method for Synthesizing a Two-Dimensional Material Consisting of Conjugated Aromatic Structures by Trimerization

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention presents a method for synthesizing two-dimensional (2D) materials made up of conjugated aromatic structures by the trimerization reaction of sodium acetylide or sodium cyanide with electron-deficient aromatic compounds. Remarkably, this process is catalyst-free and can be carried out at room temperature, resulting in the formation of large, sheet-like organic frameworks. These newly created 2D materials, such as benzene-triazine heteroaromatic sheets, feature customizable pore structures and are processable for various advanced applications.

Use CasesContent extracted from patent full text and abstract with AI.

• Molecular sieves or membranes for selective filtering of small molecules (e.g., separation of dyes or contaminants from liquids)
• Storage and controlled release systems for molecular agents (such as drug delivery or sensor applications)
• Membranes for separation of nanoparticles from solutions
• Components in electronics or photonics where 2D organic materials are advantageous (such as sensors, transistors, optoelectronic devices)
• Platforms for catalysis or immobilization of functional molecules
• Support layers for molecular or nanoparticle intercalation studies

BenefitsContent extracted from patent full text and abstract with AI.

• Catalyst-free synthesis, reducing costs and avoiding metal contamination
• Reactions proceed at room temperature, making the process energy-efficient and scalable
• Process produces sheet-like 2D materials with customizable pore sizes and chemical structures
• Good selectivity in filtering: small molecules can intercalate but larger nanoparticles (e.g., 5 nm gold) are excluded
• Potential for gram-scale (large-quantity) production
• Versatility in structural modification by choosing different electron-deficient aromatic starting materials
• High chemical and thermal stability, as demonstrated in experimental analysis
