✦ Synopsis

Abstract

Network formation: Comicellization of polystyrene‐block‐polyethylene oxide (PS–PEO) with non‐ionic surfactants leads to the formation of networks and chains of spheres. The aqueous network solutions are responsive to dilution, undergoing morphological transformations to cylinders with Y junctions and both two‐ and three‐dimensional toroids (see figure).magnified image

## Abstract A supramolecular AB diblock copolymer has been prepared by the sequential self‐assembly of terpyridine end‐functionalized polymer blocks by using Ru^III^/Ru^II^ chemistry. By this synthetic strategy a hydrophobic poly(ferrocenylsilane) (PFS) was attached to a hydrophilic poly(ethylene o
