Designing ultrastrong near-IR (NIR) absorbing organic semiconductors is a critical prerequisite for sensitive NIR thin film organic photodetectors (OPDs), especially in the region of beyond 900 nm, where the absorption coefficient of com. single crystalline silicon (c-Si) is below 103 cm-1. Herein, a pyrrolo[3,2-b]thieno[2,3-d]pyrrole heterocyclic core (named as BPPT) with strong electron-donating property and stretched geometry is developed. Relative to their analog Y6, BPPT-contained mols., BPPT-4F and BPPT-4Cl, show substantially upshifted and more delocalized highest occupied MOs, and larger transition dipole moments, leading to bathochromic and hyperchromic absorption spectra extending beyond 1000 nm with very large absorption coefficients (up to 3.7-4.3 x 105 cm-1) as thin films. These values are much higher than those (104 to 1 x 105 cm-1) of typical organic semiconductors, and 1-2 orders higher than those of com. inorganic materials, such as c-Si, Ge, and InGaAs. The OPDs based on BPPT-4F or BPPT-4Cl blending polymer PBDB-T show high detectivity of above 1012 Jones in a wide wavelength range of 310-1010 nm with excellent peak values of 1.3-2.2 x 1013 Jones, resp., which are comparable with and even better than those com. inorganic photodetectors.
