Abstract
The self-assembly of a metallo-supramolecular PS-[Ru]-PEO block copolymer, where -[Ru]- is a bis-2,2':6',2 ''-terpyridine-ruthenium(II) complex, in thin films was investigated. Metallo-supramolecular copolymers exhibit a different behavior as compared to their covalent counterparts. The presence of the charged complex at the junction of the two blocks has a strong impact on the self-assembly, effecting the orientation of the cylinders and ordering process. Poly(ethylene oxide) cylinders oriented normal to the film surface are obtained directly regardless of the experimental conditions over a wide range of thicknesses. Exposure to polar solvent vapors can be used to improve the lateral ordering of the cylindrical microdomains. (C) 2008 Wiley Periodicals, Inc.
