Color-tunable lanthanide metal-organic framework gels.

ABSTRACT: Fluorescence significantly improves the performance of gels. Various strategies, such as embedment and crosslinking, have been used to integrate extrinsic luminophores into gel systems, but the procedures are usually complex. Herein, for the first time, we report gels with intrinsic and tunable emission color prepared with 5-boronoisophthalic acid (5-bop) and Eu³⁺, Tb³⁺, and/or Dy³⁺ similar to the procedure for the preparation of metal-organic frameworks (MOFs). The single-metal gels exhibit intrinsic trichromatic fluorescence, due to which full-color emissions are readily obtained by tuning the type and/or ratio of Ln³⁺ ions to prepare mixed-metal gels. The emission is governed by an antenna effect and is thus excited with single-wavelength at 2
