Porphyrins, or more generally, porphyrinoids, have played a big role as chromophores in sensing applications. This is due to the intense absorption they exhibit over a wide section of the UV-vis spectrum, their large fluorescence yields, high chemical stability, and the multiple options for functionalization. Therefore, porphyrinoids and their metal complexes have been used as optical chemosensors for a range of analytes. This chapter provides some details on the characteristic of these indicators for sensing high pH levels, including options for tuning and matrix immobilization.
