Abstract

Chemical control of the endohedral volume of single-wall carbon nanotubes (SWCNTs) via liquid-phase filling is demonstrated to be a facile strategy to controllably modify properties of the nanotubes in manners significant for processing and proposed applications. Encapsulation of over 20 different compounds with distinct chemical structures, functionalities, and effects are demonstrated in multiple diameter ranges of SWCNTs with the ability to fill the endohedral volume dependent near solely on the availability of the core volume and compatibility of the molecules size with the cavity cross-section. Through the exclusion of ingested water with aqueous dispersion and the ability to selectively determine the endohedral chemical environment, significant improvements to optical properties of dispersed SWCNTs such as optical transition linewidths and fluorescence intensities are observed. Examples of tailoring modified properties towards applications or improved processing from simple endohedral passivation to selected property enhancement are discussed.
