N2 - The specificity of chemical sensors ceased in the last years to be a fundamental feature due to the uprising of many applications, such as electronic noses, which require the presence of broad selectivity sensors. For these applications, the attention is paid to the development of sensors whose broad selectivity can be enhanced towards some classes of compounds. Among the materials used for the scope, porphyrins have shown a good versatility to be modified in order to cope with different applications. In this paper, an extensive study of the sensitivity variations induced by modifications of the basic porphyrins, used as coating of QMB sensors, is presented and discussed.
