Synthesis and thermal and photochemical transformations of carboxy-containing polyimide derivatives with norbornene side fragments

Bromine-containing polyetherimides with pendant adamantane and fluorene moieties: Synthesis and chemical transformations

“…In particular, we showed recently that the APIs with side methacrylate and 1,1,2,3,3 pentafluoro 1,6 heptadiene groups enable the design of negative pho toresists with high lithographic parameters [1,2]. However, the APIs known to date have insufficient solubility, which limits their application in microelec tronics.…”
