Isostructural lanthanide metal–organic
frameworks (MOFs)
are synthesized through the spontaneous self-assembly of H<sub>3</sub>BTPCA (1,1′,1″-(benzene-1,3,5-triyl)tripiperidine-4-carboxylic
acid) ligands and lanthanide ions (we term these MOFs <b>Ln-BTPCA</b>, Ln = La<sup>3+</sup>, Tb<sup>3+</sup>, Sm<sup>3+</sup>, etc.).
Prompted by the observation that the different lanthanide ions have
identical coordination environment in these MOFs, we explored and
succeeded in the preparation of mixed-lanthanide analogues of the
single-lanthanide MOFs by way of in situ doping using a mixture of
lanthanide salts. With careful adjustment of the relative concentration
of the lanthanide ions, the color of the luminescence can be modulated,
and white light-emission can indeed be achieved. The mechanisms possibly
responsible for the observed photophysical properties of these mixed-lanthanide
MOFs are also discussed.
