At Kanto Chemical, we have been selling "cross-linked hexaaryl bisimidazole compounds" developed by Professor Jiro Abe and others at Aoyama Gakuin University. We have now conducted new molecular design and commercialized PY-1, PR-1, and PB-1, which have entirely new molecular frameworks and exhibit photochromic properties under sunlight. Unlike the previously released HABI type, this product group shows good photochromic properties under sunlight. Additionally, by suppressing the residual of the coloring agent, we aim to enhance the speed of color fading and improve the repeatability characteristics. These compounds are colorless in toluene solution, but under sunlight, PY-1 turns "yellow," PR-1 turns "red," and PB-1 turns "blue," demonstrating rapid photochromic properties that quickly fade when sunlight is blocked. 【Features】 ■ High-speed photochromic properties ■ High durability ■ Reactivity under sunlight For more details, please download the catalog or feel free to contact us.

This is a "ionic polymer gelling agent" of the chemical gel type that can maintain gel properties even at high temperatures. 【Features】 ■ Capable of gelling organic solvents and ionic liquids ⇒ Enables gelling of electrolytic solutions ■ Forms ionic gels ⇒ Maintains conductivity ■ Two-component irreversible reaction type chemical gel ⇒ Maintains gel state at high temperatures For more details, please download the catalog or feel free to contact us.

Ionic liquids possess characteristics such as "low volatility and flammability," "high ionic conductivity," "high thermal stability," and "excellent electrochemical properties," and are expected to be materials in a wide range of fields, including next-generation environmental and energy-related areas. 【Features】 ■ Phosphonate-based ionic liquids These are phosphonate-based ionic liquids that are actively researched by Hiroyuki Ohno and others at Tokyo University of Agriculture and Technology. They are composed of phosphonic acid derivatives as anions, which are known to dissolve cellulose under mild conditions. ■ Iodine-based ionic liquids These are ionic liquids with iodide as the anion. They are compounds that have been studied in fields such as dye-sensitized solar cells, but some products have shown discoloration due to iodine. This product is a high-purity ionic liquid with minimized coloration. Kanto Chemical offers a variety of ionic liquids beyond those mentioned above.
