Low-voltage, low-cost, high-performance monolayer field-effect transistors are demonstrated, which comprise a densely packed, long-range ordered spin-coated from core-cladding liquid-crystalline pentathiophenes and solution-processed high-k HfO2 -based nanoscale gate dielectric. These light-sensitive able to function as reporters convert analyte binding events into electrical signals with ultrahigh sensitivity (≈10 ppb).
