Abstract

A solution processable decyl alkyl chain functionalised 9,10-ter-anthryleneethynylene (D_3A) amorphous organic semiconductor, endowed with good stability in air, has been investigated as NO_x OTFT sensor. The D_3A 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.
