Description

9-[2-(Trimethoxysilyl)Ethyl]-9H-Carbazole is a high-purity organosilane coupling agent that integrates the robust photophysical properties of a carbazole moiety with a reactive trialkoxysilyl group. This compound matters for its unique ability to act as a molecular bridge, forming covalent bonds between inorganic substrates and organic polymers or functional materials. It is essential for manufacturers and R&D teams in the advanced materials, electronics, and specialty coatings sectors seeking to enhance adhesion, modify surface properties, and develop novel hybrid materials.

Application

• As a surface modification agent for silica, glass, and metal oxides to improve polymer adhesion and compatibility.
• As a key monomer or crosslinker in the synthesis of advanced organic-inorganic hybrid (OIH) materials and sol-gel coatings.
• In the formulation of high-performance adhesives, sealants, and encapsulants for electronic and optoelectronic devices.
• For the functionalization of nanoparticles (e.g., quantum dots, SiO2) to impart specific solubility or reactivity for composite applications.
• As a building block in organic electronics, such as in hole-transporting layers for OLEDs or perovskite solar cells, due to the carbazole unit's charge-transport capabilities.
• In the development of specialty silicones and silicone-modified polymers with enhanced thermal and mechanical properties.
• For chromatography stationary phase modification to create phases with specific selectivity.
• In corrosion-resistant coating systems for metals, where it promotes strong interfacial bonding.

Quality Control

Our 9-[2-(Trimethoxysilyl)Ethyl]-9H-Carbazole is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, identity, and consistency. We provide comprehensive Certificates of Analysis (COA) upon request, detailing key parameters such as assay, impurity profile, and specific tests relevant to its application as a functional silane. Our quality commitment supports your needs for reliable performance in sensitive formulations and advanced material synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity. Keep away from heat, sparks, and open flame.
