Electroactive carbon nanoforms: a comparative study via sequential arylation and click chemistry reactions

Abstract

Carbon nanoforms behave differently in sequential arylation-click chemistry reactions, which impact on their properties.

Carbon Nanotubes Conjugated with Triazole‐Based Tetrathiafulvalene‐Type Receptors for C60 Recognition

“…Thermogravimetric analysis (TGA) measurements were performed in order to evaluate the degree of functionalization (Figures S4 and S5). As expected, a higher degree of functionalization was obtained for SWCNT‐1 when compared to MWCNT‐1 . In contrast, a similar weight loss is observed in MWCNT‐2 compared to SWCNT‐2 under the same experimental conditions, what involves a better efficiency in the CuAAC of MWCNT.…”

“…In a similar manner, the two different contributions to the N 1s energy level signal for SWCNT‐2 and MWCNT‐2 corroborated the formation of the triazole rings as a consequence of the CuAAC reaction . The peak corresponding to the S 2p at 170 eV was an evidence of the presence of the exTTF motifs …”

“…Once compound 4 was synthesized, CNT endowed with protected alkyne functionalities ( SWCNT‐1 and MWCNT‐1 ), previously obtained by following a Tour arylation reaction, were suspended in N ‐methyl‐2‐pyrrolidone (NMP) and reacted with tetrabutylammonium fluoride (TBAF) to deprotect the alkyne groups, which were subsequently reacted with 4 in a new Cu I ‐catalyzed 1,3‐dipolar cycloaddition process (Scheme ).…”

“…These carbon nanotube‐C 60 nanohybrids were assembled in a tricomponent electroactive system with the aid of covalent and non‐covalent methodologies. The CNT‐exTTF tweezer nanoconjugates were synthesized by a well established methodology in the covalent chemistry of carbon nanoforms that combines arylation under Tour conditions and Cu I ‐catalyzed azide‐alkyne cycloaddition (CuAAC) reactions . The host‐guest complexes formed between the CNT‐exTTF tweezer and C 60 were investigated by UV‐Vis spectroscopy.…”

“…the ''patching'' successfully modified the whole system [61]. With respect to ''patching'', they also synthesized an electron-donor-acceptor nanohybrid via non-covalent interactions [62].…”
