    Abstract:
    Diamondoids, sp3 -hybridized nanometer-sized diamond-like hydrocarbons (nanodiamonds), difunctionalized with hydroxy and primary phosphine oxide groups, enable the assembly of the first sp3 -C-based chemical sensors by vapor deposition. Both pristine nanodiamonds and palladium nanolayered composites can be used to detect toxic NO2 and NH3 gases. This carbon-based gas sensor technology allows reversible NO2 detection down to 50?ppb and NH3 detection at 25-100?ppm concentration with fast response and recovery processes at 100?°C. Reversible gas adsorption and detection is compatible with 50?% humidity conditions. Semiconducting p-type sensing properties are achieved from devices based on primary phosphine-diamantanol, in which high specific area (ca. 140?m2 ?g-1 ) and channel nanoporosity derive from H-bonding.© 2019 Wiley-VCH Verlag GmbH & Co.
