Hexamethoxytriphenylene

Updated: 2026-08-06

Overview

Hexamethoxytriphenylene (HMT) is an organic compound derived from the triphenylene core structure, substituted with six methoxy groups. This modification enhances its electronic properties, making it valuable in advanced materials applications. Its highly conjugated π-electron system contributes to its stability and utility in electronic devices. HMT is primarily synthesized through organic reactions involving triphenylene derivatives and methoxy group introductions. Due to its unique properties, it is widely studied in materials science, particularly for its potential in optoelectronic applications.

Physical and Chemical Properties

Hexamethoxytriphenylene appears as a white to pale yellow crystalline powder, with a molecular weight of 408.44 g/mol. It is soluble in common organic solvents such as chloroform and dichloromethane but exhibits negligible solubility in water. The compound's melting point is approximately 200-220°C, reflecting its stable aromatic structure. Key chemical properties include its highly conjugated system, which facilitates electron delocalization. This makes HMT suitable for applications requiring charge transport, such as organic semiconductors. The methoxy substituents further influence its electronic behavior, enhancing its compatibility with other organic materials.

Main Applications

Hexamethoxytriphenylene is primarily used in the development of organic semiconductors, where its conjugated system enables efficient charge transport. It is also employed in liquid crystal displays (LCDs) as a component of photoconductive materials, improving display performance and stability. Additionally, HMT is explored in research for potential uses in organic light-emitting diodes (OLEDs) and photovoltaic devices. Its ability to form stable thin films and interact with other organic compounds makes it a versatile material in advanced electronics and optoelectronics.

Safety and Storage

While Hexamethoxytriphenylene is relatively stable under normal conditions, proper handling is essential to minimize risks. Avoid inhalation or direct skin contact, as the compound may cause irritation. Use in well-ventilated areas and wear appropriate personal protective equipment (PPE). Storage should be in a cool, dry place, away from light and moisture to prevent degradation. Containers must be tightly sealed to avoid contamination. For large-scale procurement, ensure compliance with local regulations regarding hazardous chemical storage and disposal.

B2B Procurement Guide

When sourcing Hexamethoxytriphenylene, prioritize suppliers with verified certifications and a track record of quality. Request a Certificate of Analysis (COA) to confirm purity and composition. Pricing varies based on purity levels and order volume, so obtain multiple quotes for comparison. Consider logistical factors such as packaging, shipping conditions, and lead times. For bulk purchases, negotiate terms for storage and delivery to align with your production schedule. Establish clear communication channels with suppliers to address any quality or delivery concerns promptly.
