Recently Poly-(styrene-b-ferrocenylsilane-b-2-vinylpyridine) (PS-b-PFS-b-P2VP) triblock copolymers have been reported to form core-shell like cylinders under certain solvent annealing conditions in thin films via microphase separation[1]. Here, we present our studies on structure formation in a similar polymer when applying thermal annealing using SAXS, GISAXS and SEM. Furthermore, we present our efforts to transfer the obtained structure into isolated core-shell nanorods by dissolving the matrix polymer in a selective solvent. [1] V. P. Chuang, C. A. Ross, J.
