Single-walled carbon nanotubes (SWCNTs) are synthesized as mixtures of varied SWCNT varieties, exhibiting drastically totally different properties, and thereby making the fabric of restricted use. Fluorene-based polymers are profitable brokers for purifying such blends by way of conjugated polymer extraction (CPE), significantly growing their software potential. Nonetheless, a restricted variety of research have devoted consideration to understanding the results of the polyfluorene spine and facet chain construction on the selectivity and separation effectivity of SWCNTs. Relating to the affect of the polymer spine, it was famous that the flexibility to extract SWCNTs with conjugated polymers could possibly be considerably enhanced through the use of fluorene-based copolymers that exhibit dramatically totally different interactions with SWCNTs relying on the kinds of monomers mixed. Nonetheless, the position of monomer facet chains stays a lot much less explored, and the data generated up to now is fragmentary. Herein, we current a brand new strategy to tailor polymer selectivity by creating copolymers of polyfluorene bearing mixed-length alkyl chains. Their thorough and systematic evaluation by experiments and modeling revealed appreciable perception into the affect of the hooked up purposeful teams on the capability of conjugated polymers for the purification of SWCNTs. Curiously, the obtained outcomes contradict the widely accepted conclusion that polyfluorene-based polymers and copolymers with longer chains all the time favor SWCNTs of bigger diameters. In addition to that, we report that the capability of such polymers for sorting SWCNTs could also be considerably enhanced utilizing particular low molecular weight compounds. The carried-out analysis offers appreciable perception into the conduct of polymers and carbon-based supplies on the nanoscale.
