WebCTC formation in solution is affected by the donor–solvent and acceptor–solvent interactions, the solvent is also expected to affect the CTC binding energy. Finally, as shown in ref. 24, the CTCs serve as interchain links, and it is not clear whether CTCs can be formed on a single chain. Therefore, the CTC formation WebTheir structures were confirmed by 1 H NMR and FTIR spectroscopy. CTC formation between Iod (acceptor) and amines on PEI (donor) was confirmed by absorption shift to 440 nm in spectral analysis ...

WebMar 5, 2024 · We find that the use of evaporation doping and higher-crystallinity material discourages CTC formation, but that even in the most favorable case of evaporation doping with high polymer crystallinity, fractional charge transfer always occurs to some extent. Finally, we show that brief thermal annealing can convert CTCs to integer charge transfer ...
