It first appeared from the Royal Society of Chemistry at http://dx.doi.org/10.1039/c6mh00230g. ; Abstract ; Reactions inside the pores of metal–organic frameworks (MOFs) offer potential for controlling polymer structures with regularity to sub-nanometre scales. We report a wet-chemistry route to poly- 3,4-ethylenedioxythiophene (PEDOT)–MOF composites. After a twostep removal of the MOF template we obtain unique and stable macroscale structures of this conductive polymer with some nanoscale regularity. ; Other ; The project is funded through the European Research Council (ERC) grant (grant number: EMATTER 280078).
