抜粋

Local chemical functionalization of single-walled carbon nanotubes has been reported to modulate their near infrared photoluminescence (PL), where defect doping creates new emissive sites on the nanotubes. Previously, we reported on proximal defect doping with the use of bis-aryldiazonium salts, which considerably red-shifted nanotube PL (>1200 nm). In this study, we achieved PL modulation with newly designed bis-aryldiazonium modifiers having meta-linked methylene spacers. The spacer length-dependent wavelength shifts were greater than those of our previous para-linkage design.
