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 via conjugated polymer extraction (CPE), enormously rising their utility potential. Nevertheless, a restricted variety of research have devoted consideration to understanding the consequences of the polyfluorene spine and facet chain construction on the selectivity and separation effectivity of SWCNTs. Concerning the affect of the polymer spine, it was famous that the flexibility to extract SWCNTs with conjugated polymers might be considerably enhanced through the use of fluorene-based copolymers that exhibit dramatically totally different interactions with SWCNTs relying on the forms of monomers mixed. Nevertheless, the function of monomer facet chains stays a lot much less explored, and the data generated to date 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 practical teams on the capability of conjugated polymers for the purification of SWCNTs. Curiously, the obtained outcomes contradict the commonly accepted conclusion that polyfluorene-based polymers and copolymers with longer chains at all times desire SWCNTs of bigger diameters. Moreover that, we report that the capability of such polymers for sorting SWCNTs could also be significantly enhanced utilizing particular low molecular weight compounds. The carried-out analysis supplies appreciable perception into the habits of polymers and carbon-based supplies on the nanoscale.
