| abstract |
The invention relates to carbon dioxide sensing compounds. In particular, the present invention relates to said sensing compounds comprising a phathalocyanine or a metal phthalocyanine. Furthermore, the invention relates to the tuning sensitivity of the phathalocyanine or the metal phthalocyanine by incorporation of amine groups and spacers. The sensing layers can be integrated on various transducers like a chemiresistor, a capacitor, a field effect transistor (FET), an optical-based sensor, or a mass-based sensor. |
