Application

1,2,3,4-Cyclobutanetetracarboxylic Dianhydride serves as a versatile reactant, predominantly used in the synthesis of biologically and pharmacologically active molecules. Its applications extend to the preparation of photosensitive polyimide materials, which are essential for crafting high-performance organic thin-film transistors. Furthermore, this compound is instrumental in the selective crosslinking of polyimide for photonic devices. Featuring a unique cis-trans-cis configuration, it facilitates the creation of polyimide films that exhibit remarkable thermal resistance and optical clarity. These films are transparent and colorless, with transmittance levels between 81.5% and 85.8%, making them ideal for high-quality display materials like liquid crystal displays. In contrast, polyimides synthesized with pyrrolidine dianhydride appear dark yellow and demonstrate reduced transmittance, ranging from 48% to 63.9%.
