✦ Synopsis

Repetitive Diels-Alder reactions' of 1,2,5,6-tetra-exo-methylenecyclooctane (3) and [2.2]-(2,3)-furanophane (6) provide novel band-type atructurea. 3 and 6 differ significantly in the relative rate of the first and second cycloaddition. Redox polymers with separate electrophores (= electroactive groups) are of fundamental and practical significance.2 A unique example is the polymeric band-type structure 1 in which scene subunits are linked with the formation of ortho-cyclophanes. We have recently prepared polymer 2 which constitutes a suitable precursor for a band structure with ortho-anthracenophane moieties.3
