Introduction. Well-defined supramolecular structures similar to those formed by spontaneous and recognitiondirected self-assembly in biopolymeric systems have not as yet been realized in synthetic macromolecules. How-ever, there are several approaches to obtain highly ordered polymeric systems both by specific interactions between functional groups and/or by taking advantage of segre-gation phenomena. 1

It is known from supramolecular chemistry that bipy-ridine oligomers exhibit spontaneous self-organization in the presence of Cu (I) ions to form a double-stranded helical complex, which possesses characteristic features remi-nescent of the DNA double helix. 2 Here we report on the application of the concepts of organic supramolecular chemistry to the formation of a “linear polymeric su-pramolecular material”(cf. ref 3) by bipyridine (bpy) metal coordination of telechelic polyethers with 6, 6'-disubsti-tuted 2, 2,-bipyridine terminal unit containing end blocks (Figure 1). This work extends our previous studies of the control of segregation and chain folding of monodisperse
