Compositions and methods are provided in which an electrical device is fabricated by incorporating macrocycles in a polymer on a substrate portion of the device, and crosslinking the polymer to form a crosslinked polymer. It is preferred that at least some of the macrocycles are relatively large, including at least six rings in the backbone of a macrocycle. It is also preferred that rings used in forming the macrocycles may be relatively large, preferably having at least six members as in phenyl rings. The intermacrocyclic links can be relatively complex, such as where four macrocycles may be coupled to a single atom or a single phenyl group. In yet other aspects, macrocycles can be heavily conjugated, with more preferred macrocycles having a completely conjugated backbone. In yet other aspects the macrocycles can have backbones with ether, carboxyl, and ethynyl groups, some of which can be used in crosslinking without reliance on an extrinsic crosslinker. In still another aspect, the macrocycles can be fabricated from a bisphenol and a difluoroaromatic compound.
