    • note
    • A Tiiii cavitand with a single P-O group functionalized with the fluorophore and three standard phenyl groups would have lead to an undesired dilution of the H-bonding perturbation on four sites, with three of them luminescence silent. On the other hand, a Tiiii cavitand bearing the fluorophore on each P-O unit would have two counter-indications: a likely self-quenching in the solid state, and a lower I/I and thus a lower s/n ratio, as only 1/4 of the signal would change upon complexation
