Advanced tetra amino (ATA-100) cobalt(II) phthalocyanine-based metallo-covalent organic polymer for sensitively detecting volatile organic compounds.

The synthesis and characterization of a novel covalent organic polymer cobalt (II) phthalocyanine () including tetra amino group is described for the first time. This covalent organic polymer (COP) is characterized by FTIR, TGA, RAMAN, PXRD, and SEM-EDS. The developed sensor is tested for acetone, ethyl butyrate, hexane, chloroform, and butyraldehyde in a range of 80-10,900 ppm. showed the highest sensitivity for ethyl butyrate. The results have confirmed the possibility of utilizing COP-based surface acoustic wave (SAW) sensors for a wide variety of applications, including indoor air quality and environmental monitoring of volatile organic compounds (VOCs).
