Patent ID: 7825404

Claim:
A structural building block comprising a substrate with a layer, wherein the layer comprises a polymer formulation, the polymer formulation comprising: about 100 parts by mass of at least one crosslinkable base; polymer selected from the group consisting of poly-4-vinylphenol, poly-4-vinylphenol-co-2-hydroxyethylmethacrylate and poly-4-vinylphenol-co-methylmethacrylate; from about 10 to about 20 parts by mass of 4 hydroxymethyl-benzyl alcohol as an electrophilic crosslinking component; and from about 0.2 to about 10 parts by mass of triphenysulfoniumhexaflat as a photo acid generator, whereby, upon a photoinduced crosslinking reaction, the layer forms a gate dielectric layer of an organic field effect transistor (OFET).
