Webtetracyanoquinodimethane (F4-TCNQ) was used as a p-type dopant because of its strong electron aﬃnity (lowest unoccupied molecular orbital: 5.2 eV).22 When the p-type semiconducting polymer, P3HT, was doped with the F4-TCNQ, the charge carrier density in the P3HT increased due to charge transfer from P3HT to F4-TCNQ. Thermal WebThe main weakness of F4-TCNQ is its high volatility,13 which makes it difficult to handle as a dopant, and may result in undesirable heterogeneities in the dopant/host layer. …
