Labeling of optically inert receptors with sensitive dyes is a popular technique used for the development of optochemical sensors. The bond with an analyte perturbs the interaction between the single components and causes a detectable change in optical features. In this paper, such strategy is further extended preparing blends of two chemoresponsive dyes: a metalloporphyrin and an acid/base indicator. Here, both the constituents can change color upon the interaction with volatile compounds, but some target...
