Abstract: We report a vapor phase molecular imprinting (MIP) technique suitable for an organic field-effect transistors (OFET)-based sensor. This OFET-based sensor using pentacene as the molecularly imprinted monomer showed enhanced selectivity to 2, 4-dinitrotoluene (DNT) vapor against various interfering analytes. This method can be extended to improve the selectivity of most OFET- and chem-resistor based sensors without adversely affecting the device's electronic properties, which is promising for the development of highly selective, low-cost, flexible OFET sensors
