The present application relates to semiconductor processing compositions comprising at least one compound containing at least one amidoxime functional group and to methods of using these compositions in semiconductor processing. The present application also describes the preparation of amidoximes for a semiconductor processing composition by (a) mixing a cyanoethylation catalyst, a nucleophile and an alpha-unsaturated nitrile to produce a cyanoethylation product; and (b) converting a cyano group in the cyanoethylation product into an amidoxime functional group.

were synthesized and purified to homogeneity. The influence of the alpha-branched acyl chains on the monolayer packing properties of these phospholipids was studied by the Langmuir-Blodgett film balance technique. NMR investigations were used for conformational studies, including the determination of rotamer populations about the dihedral angles (theta 2, theta 4 and alpha 1) in the glycerol region of

The synthesis of a diketopyrrolopyrrole (DPP)-based semiconducting polymer bearing thermocleavable side chains is described. This polymer can be converted into a native semiconductive polymer by thermal annealing at 200 °C. The resulting side chain-free polymer showed a good p-type semiconductor performance in organic thin film transistors.
