Strong Electron-Deficient Polymers Lead to High Electron Mobility in Air and Their Morphology-Dependent Transport Behaviors

Planar backbone, locked conformation, and low lowest unoccupied molecular orbital level provide polymer F4BDOPV‐2T with ultrahigh electron mobilities of up to 14.9 cm2 V−1 s−1 and good air stability. It is found that the nonlinear transfer curves can be tuned to near‐ideal ones by changing fabricati...

Description
Summary:Planar backbone, locked conformation, and low lowest unoccupied molecular orbital level provide polymer F4BDOPV‐2T with ultrahigh electron mobilities of up to 14.9 cm2 V−1 s−1 and good air stability. It is found that the nonlinear transfer curves can be tuned to near‐ideal ones by changing fabrication conditions, indicating that film morphology largely contributes to the nonlinear transfer curves in high‐mobility conjugated polymers.
