Abstract

The anthracene (QCa1) and pyrazoline (QCa2) derivatives display Ca ²⁺- 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.
