High-T, metal oxide superconductors, first discovered by Bednorz and Miiller, ['] could revolutionize communication, computation, transportation, and energy transmission technology. For each application the material has to be fabricated in suitable shapes and forms. In this respect polymers are very interesting because their use as thickening agents for precursor solutions ['] or as complexing agents for metal ions permits the preparation of superconducting material with different shapes.r31 A polymer-metal-complex (PMC) precursor process for the synthesis of high-T, superconductors including Y-Ba-Cu-0 (123 compound), Y-Ba-Cu-Ag-0, Bi-Sr-Ca-Cu-0, Pb-Bi-Sr-Ca-Cu-0 and other materials has recently been reported.I3I This technique has now been extended by using structured PMC's. The particularly novel concept here is to achieve, via supramolecular organiza-tion14] of the PMC precursor, a specific microscopic and macroscopic morphology of the superconducting material.
