Abstract
Organic color center-tailored carbon nanotubes, particularly semiconducting single-walled carbon nanotubes, are of significant interest for imaging, sensing, and quantum information processing applications. A high-yield, simple, one-pot synthetic route for producing these materials exceeding the current μg/mL scale is provided. Adding an acid solution of raw carbon nanotubes, nitrite, and an aniline derivative into a reactive solvent, such as water, results in covalently bonded organic color center-tailored nanotubes. No radical initiator or heating is required for the reaction. The chemistry works for all the nanotube chiralities investigated. The synthesized materials are neat solids that can be readily dispersed in either water or an organic solvent using a surfactant or polymer depending on the specific application. The OCC-products can also be further sorted into single chirality-enriched fractions with defect-specific photoluminescence that is tunable over approximately 1100 to approximately 1550 nm.
