The use of lanthanide luminescence as a reporter in the solid state: Desymmetrization of the prochiral layers of γ-zirconium phosphate/phosphonate and circularly polarized luminescence.

Solid-state CPL measurements were performed for the first time on hybrid, laminar materials based on γ-ZrP pillared with organic diphosphonates. Ad hoc optically pure diphosphonates were synthesized and the luminescence properties of their complexation with Tb(III) were verified in solution. CD and CPL measurements showed that the bistriazolylpyridine chromophores bonded to the metal provided an effective chiral environment that produced significant signals.
