Article Synopsis
- Recent research highlights a novel method for non-covalently functionalizing single wall carbon nanotubes (SWCNTs) using thienothiophene (TT) derivatives, eliminating the need for external binding agents.
- Newly synthesized TT derivatives (HYBRID 1-3) were directly attached to SWCNTs, showcasing clear attachment through TEM imaging, with sulfur atoms in TT aiding in the adsorption of gold nanoparticles for visual confirmation.
- Further analyses, including molecular dynamics simulations and various imaging techniques (SEM, TEM, AFM), confirmed strong surface interactions between the TTs and SWCNTs, revealing significant binding energies and close proximity through advanced computational methods.
A wide series of 10 new triphenylamine (TPA)/4,4'-dimethoxytriphenylamine (TPA(OMe))-functionalized thieno[3,2-]thiophene (TT) fluorophores, and , bearing different electron-donating and electron-withdrawing substituents (-PhCN, -PhF, -PhOMe, -Ph, and -CH) at the terminal thienothiophene units were designed and synthesized by the Suzuki coupling reaction. Their optical and electrochemical properties were investigated by experimental and computational studies. Solid-state fluorescent quantum yields were recorded to be from 20 to 69%, and the maximum solution-state quantum efficiency reached 97%.
