Two donor-acceptor-donor (D-A-D) type low-bandgap small mols., M1 and M2, with bis(2-thienyl)-N-alkylpyrrole (TPT) as the donor and thieno[3,4-b]thiadiazole (TT) as the acceptor were designed and synthesized. The absorption, transmission, electrochem., thermal and film properties were studied. The compounds showed panchromatic absorption in the spectral range of 300-1000 nm. They exhibited semi-transparent property in the visible region (400-700 nm). Small mol. photodetectors (SMPDs) based on M1 and M2 were fabricated and studied. For the SMPD with BCP as the hole blocking layer (HBL), a detectivity of 5.0 × 1011 Jones at 800 nm at -0.1 V was obtained, which is among the highest detectivities reported for NIR SMPDs. With a sufficiently thin Ag electrode, visibly transparent PDs with an average transmittance of 45% in the visible region were obtained for the 1st time. The transparent PDs exhibited fairly constant and high detectivity of (1-10) × 1011 Jones over λ = 300-900 nm. Side chains of the compounds exhibited a great influence on the device performance, which could be assigned to their film absorption coefficient, mol. packing and active layer morphol.
