The Influence of the Nature of the Polymer Incorporating the Same A₃B Multifunctional Porphyrin on the Optical or Electrical Capacity to Recognize Procaine.

ABSTRACT: The multifunctionality of an A₃B mixed-substituted porphyrin, namely 5-(4-carboxyphenyl)-10,15,20-tris(4-methylphenyl)porphyrin (5-COOH-3MPP), was proven due to its capacity to detect procaine by different methods, depending on the polymer matrix in which it is incorporated. The hybrid nanomaterial containing k-carrageenan and AuNPs (5-COOH-3MPP-k-carrageenan-AuNPs) was able to optically detect procaine in the concentration range from 5.76 × 10^-6 M to 2.75 × 10^-7 M, with a limit of detection (LOD) of 1.33 × 10^-7 M. This method for the detection of procaine gave complementary results to the potentiometric one, which uses 5-COOH-3MPP as an electroactive material incorporated in a polyvinylchloride (PVC) membrane plasticized with o-NPOE.
