Application

1,2,3,4-Cyclobutanetetracarboxylic Dianhydride (purified by sublimation) serves crucial roles in multiple advanced material applications. It acts as a vital reactant in preparing biologically and pharmacologically active molecules, and is essential in synthesizing photosensitive polyimide materials, which are integral for high-performance organic thin-film transistors. Furthermore, it is utilized in the selective crosslinking of polyimide for photonic devices. This anhydride, with its unique cis-trans-cis configuration, facilitates the production of polyimide films known for their excellent heat resistance, transparency, and colorlessness. These properties make them ideal for use in high-quality display materials, such as liquid crystal displays, with a transmittance of 81.5% to 85.8%. In contrast, alternative polymers made with pyrrolidine dianhydride exhibit a dark yellow coloration and significantly lower transmittance, ranging from 48% to 63.9%.
