The concept of sensing metal cations by using fluorescence changes in non‐aggregating AzaPc molecules that exhibit significant intramolecular charge transfer (ICT) in the OFF state was demonstrated by binding Na + and K + to an aza[15]crown‐5 recognition moiety. It is important to note that this concept works not only in organic solvents, but also in water after the sensor molecules are incorporated into silica nanoparticles.
