The anthracene (QCa1) and pyrazoline (QCa2) derivatives display Ca²⁺-induced enhancements of fluorescence quantum yields (Φ_F), by factors of 16 and 92, respectively; the binding selectivities (vs.Mg²⁺ and H⁺) and characteristics of the electronic (absorption and emission) spectra (except Φ_Fmax.) are reasonably predictable from simpler model compounds.
