Description and Uses

Cyclobutane-1,2,3,4-tetracarboxylic dianhydride (CBDA) is an anhydride with a cis-trans-cis configuration. It can be used to synthesise polyimide films. Polymer films have excellent heat resistance, are transparent and colourless, with transmittance ranging from 81.5% to 85.8%, and are suitable for use in high quality display materials such as liquid crystal displays. The polymers made with pyrrolidine dianhydride instead of CBDA are dark yellow in colour and have a lower transmittance in the range of 48% to 63.9%.

Reactant for:

  • Preparation of biologically and pharmacologically active molecules
  • Preparation of photosensitive polyimide material for high performance organic thin-film transistors
  • Selective crosslinking of polyimide for photonic devices
