Enhance of Sensitivity of Corrole Functionalized Polymeric Microspheres Coated Quartz Microbalances

An innovative and efficient β-functionalization of [5,10,15-tris-(4-methylphenyl)corrolato]Cobalt derivatives introduced an acrolein substituent, which allowed the copolymerization with pure acrolein. The obtained hybrid microparticles have been used as sensing materials of quart microbalance gas sensors. The sensing properties have been tested by exposure to different volatile organic compounds chosen as model analytes. Results show an improved sensitivity of the hybrid microparticles respect to the individual constituents.
