Description
Deepak Bansal, Sujithkumar Ganesh Moorthy, Marcel Bouvet and Nicolas Boscher make nickel porphyrin polymers for ammonia sensors and show they can flip a device's electrical polarity by design. The polymers sit as a top layer over a copper phthalocyanine film in a two-layer junction. Changing the aryl groups at one position on the porphyrin is the lever.
Polymers with electron-donating groups gave p-type behaviour, while those with electron-withdrawing groups gave n-type behaviour. Many checks, from mass spectrometry to photoelectron spectroscopy, plus density functional calculations, explain the shift through coupling and charge spread in the films. All devices sensed ammonia well, and one pairing gave the highest sensitivity in the set.
