Abstract
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. On the other hand, the attention is paid to the development of sensors whose broad selectivity can be enhanced towards some classes of compounds. Among the materials used /or the scope, the 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, are presented and discussed.
