Abstract
Corrole derivatives are a versatile class of coordination complexes successfully exploited in different applications, ranging from medical to environmental fields, due to their peculiar tunable properties. Herein, we report novel N-alkyl corroles-based gravimetric sensors obtained by the deposition of twelve different macrocycles on quartz microbalances (QMBs). Sensors were tested against 17 VOCs and 4 gases, showing notable sensitivities, particularly to CO, NO, and ethanolamine. Data analysis revealed clear trends related to the alkyl chain structure, confirmed through correlations with linear solvation equation relationship (LSER) parameters. Principal Component Analysis enabled the clustering of com-pound families and discrimination along homologous series (e.g. class of alcohols). The sensors demon-strated strong potential for analyte differentiation in complex mixtures as demonstrated by a study cases where methanol content was estimated in both real and synthetic wine samples.
