Abstract
A water soluble naphthalenediimide (NDI) selectively interact with small diameter single-walled carbon nanotubes (SWCNTs), as demonstrated by Raman, along with absorption and emission spectroscopies.
Highlights
Some of the authors of this publication are working on these related projects: Nanoplasmonic hybrids for artificial photosynthesis View project
While the use of n-type semiconductors for selective adsorption on SWCNTs have been successfully reported,[15,16] here we discuss the non-covalent interaction of a water soluble naphthalenediimide derivative (NDI1) with SWCNTs
The first aim of this investigation was to focus on the solubilization of SWCNTs using NDI1 as a surfactant
Summary
Some of the authors of this publication are working on these related projects: Nanoplasmonic hybrids for artificial photosynthesis View project. Carbon Nanotubes (CNTs) are amongst the more used nanomaterials of the last decades They have been applied to different fields, including electronics, solar cells, catalysis and nanomedicine.[1,2] One of the main drawbacks for their use in most applications is the strong tendency to aggregate and the poor solubility in any solvent, organic or aqueous. While the use of n-type semiconductors for selective adsorption on SWCNTs have been successfully reported,[15,16] here we discuss the non-covalent interaction of a water soluble naphthalenediimide derivative (NDI1) with SWCNTs. The naphthalenediimides are the smallest n-type semiconductor analogs in the family of rylenes.[17] Their shape and rich π system makes them as good candidates for the formation of interesting hybrid materials with SWCNTs. Only a few articles employing NDIs as surfactants for CNTS have been reported.[18,19] In this work, we have used a bis-cationic NDI
