A tetrathienopyrrole-based ladder-type donor polymer for high-performance organic near-infrared cavity detectors

Ladder-type extension of a push–pull donor polymer affords enhanced peak external quantum efficiencies in microcavity organic photodetectors, with detectivities ranging from 1.07 × 10 12 to 1.82 × 10 10 Jones in the 900–1400 nm regime.
