Ladder conjugated polypyrrones are readily synthesized by condensation of air-stable tetraamines and naphthalene-1,4,5,8-tetracarboxylic acid dianhydride. These rigid-rod ladder polymers are soluble in many common organic solvents and can be cast into thin films for device applications. These polymers are electron-deficient, have a high electron affinity (～4.0 eV) and electron mobility (2.0 × 10^?3 cm² V^?1 s^?1) and show a broad absorption in the visible and near-infrared spectral region. The bulk-heterojunction photovoltaic photodetectors using the electron-deficient polypyrrone as an acceptor together with poly(3-hexyl thiophene) as a donor exhibited the spectral response from 300 to 900 nm and specific detectivity in an order of 10¹⁰ Jones at 800 nm.
