|Title:||Lanthanide Coordination Polymers of Mixed Phthalate/Adipate for Ratiometric Temperature Sensing in the Upper-Intermediate Temperature Range|
|Abstract:||© 2018 American Chemical Society. Based on the mixed phthalate (phth2-) and adipate (ad2-), [Nd2(ad)(phth)2(H2O)4] (I) and [Ln(ad)0.5(phth)(H2O)2] (Ln = EuIII(II), GdIII(III), TbIII(IV), DyIII(V), ErIII(VI), TmIII(VII), 1EuIII:10TbIII(VIII), 3EuIII:10TbIII(IX), and 5EuIII:10TbIII(X)) were synthesized and characterized. Complexes VIII-X show excellent ratiometric temperature sensing behavior in physiological and higher temperature ranges (303-423 K) rendered by the TbIII-to-EuIIIenergy transfer process. The efficiency of the process as illustrated through the lifetime measurements depends on both the EuIII:TbIIImole ratio and the temperature. The performance of X in terms of relative sensitivity (Sr), temperature resolution, and measurement repeatability were determined, revealing the maximum Sr(Sm) of 1.21%·K-1at 303 K with reliable temperature resolution and excellent repeatability.|
