Cyclobutane-1,2,3,4-tetracarboxylic dianhydride was used to synthesize polyimide films and poly(amic acid) having liquid crystal alignment layers.
1,2,3,4-Cyclobutanetetracarboxylic dianhydride serves as a versatile tetrafunctional building block for constructing rigid, polycyclic architectures. Its four adjacent anhydride groups enable sequential functionalization with nucleophiles such as amines and alcohols, facilitating the synthesis of complex heterocycles and high-performance polymers. The molecule exhibits excellent bench stability and reacts cleanly under mild conditions, offering predictable regioselectivity in multistep syntheses.
