| Abstract: | Rational selection and modification of rare earth metal centers and photoactive organic linkers enables designable multiphotofunctionality to come to fruition in new hybrid coordination polymer materials. By using a viologen‐functionalized diphosphonate linker, two terbium phosphonate compounds ( Tb‐1 and Tb‐2 ) have been constructed, which display reversible photochromic reactions in response to UV light and soft X‐ray irradiation. In addition, the photo‐induced electron‐transfer reaction can modulate the luminescent emission to thus realize photoluminescence switching behavior. Furthermore, both terbium phosphonates can serve as highly sensitive sensors to probe Cu2+ in solution through their luminescence. Thus, they represent the first photochromic examples of lanthanide phosphonate‐based materials with photomodulated luminescence and sensitive detection of metal ions. |
