Synthesis and characterization of new copolyacrylates containing porphyrin units as pendant groups and their use as sensors

Novel copolyacrylates contg. various molar ratios of 5,10,15-tri[p-(9-methoxytriethylenoxy)phenyl]-20-(p-acryloxyphenyl)porphyrin units in the chains have been synthesized, and their chem. structure was detd. by NMR and MALDI-TOF mass spectrometry. Sensing response of the synthesized copolymers has been tested for trifluoroacetic and hydrochloric acids and nitrogen dioxide analytes. The reported sensing data indicate that porphyrin units are interacting with analytes in a reversible fashion.
