Abstract

A flow functionalization route has been employed to derivatize single wall carbon nanotubes (SWCNT) by thienylphenyl groups. TheSWCNT derivatives in the most soluble fraction have been characterized by thermogravimetric analysis, DLS analysis, DFT calculations,UV-vis-NIR, microRaman and IR spectroscopies to study the degree of functionalization, the concentration of SWCNTs in solution, thedimension of the aggregates in solutions, the density of defects, and the presence of the thienylphenyl groups. Thin film heterojunctionsmade of SWCNT derivatives and poly(3-hexylthiophene) (P3HT) have been prepared by various methods employing the Langmuir Shaefertechnique, spin coating and thermal annealing processes. By comparing the batch and the flow functionalizations a trade-off betweensolubility, processability and the thin film opto-electronic properties has been found as a result of the degree of functionalization
