Randomized trial demonstrates improved luminescence in ambipolar polymers, highlighting new semiconductor potentials.
Key Points
The study aims to address the challenges of achieving both high mobility and strong luminescence in DPP-based semiconductors.
Synthesized two novel DPP-derived polymers (PTFBVDPP-V and PTFBVDPP-TVT) via Stille coupling.
Utilized precise donor-acceptor engineering to improve polymer performance.
Characterized electron and hole mobility and photoluminescence quantum yield in various conditions.
PTFBVDPP-V achieved an electron mobility of 2.61 cm²·V⁻¹·s⁻¹ but showed negligible emission.
PTFBVDPP-TVT exhibited ambipolar transport with electron mobility of 1.15 cm²·V⁻¹·s⁻¹ and hole mobility of 1.52 cm²·V⁻¹·s⁻¹, along with photoluminescence quantum yield of 6.5%.
A maximum product of photoluminescence quantum yield and electron mobility exceeding 10⁻² cm²·V⁻¹·s⁻¹ was established, outperforming traditional DPP-based systems.
