WebSep 29, 2014 · An electroactive COF: A two-dimensional covalent organic framework (COF) containing well-known tetrathiafulvalene (TTF) units is synthesized (see figure). The presence of TTF units endows the TTF-COF with electron-donating ability, and the open frameworks of TTF-COF are amenable to doping with electron acceptors (e.g., iodine).

WebMay 16, 2024 · The open frameworks of TTF-COF are amenable to doping with electron acceptors (e.g., iodine), and the cond. of TTF-COF bulk samples can be improved by doping. The results open up a reliable route for the prepn. of well-ordered conjugated TTF polymers, which hold great potential for applications in fields from mol. electronics to energy storage. WebTTF-COF thin film allows the diffusion of dopants such as I2 and tetracyanoquinodimethane (TCNQ) for redox reactions, while the closely packed 2-dimensional grid sheets facilitate the cross-layer delocalization of thus-formed TTF radical cations to generate more conductive mixed-valence TTF species, as is verified by UV-visible-NIR and ESR spectra.
