Abstract :
A solution processable decyl alkyl chain functionalised 9,10-ter-anthryleneethynylene (D3A) amorphous organic semiconductor, endowed with good stability in air, has been investigated as NOx OTFT sensor. The D3A OTFT operated at room temperature exhibited differential sensitivity to NO and NO2. NO2 detection down to 250 ppb could be achieved with very low cross sensitivity to interfering species such as carbon monoxide and hydrogen sulphide.
