文摘
- •
Three polymers based on BDD unit were synthesized and characterization.
- •
This is the first investigation on the OTFTs of BDD-based polymers.
- •
The OTFT performances were optimized by tailoring structure and annealing.
- •
The optimized P3 exhibited balanced hole and electron transport.
- •
The phototransistors showed a high photocurrent/dark-current ratio of 6.4 × 103.
