Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The luminescent properties of a family of lanthanide metal–organic frameworks <bold>LnL</bold> (<bold>Ln</bold>=Y, La–Yb, except Pm; <bold>L</bold>=4, 4′‐({2‐[(4‐carboxyphenoxy)methyl]‐2‐methylpropane‐1, 3‐diyl}bis{oxy})dibenzoic acid) have been explored, and the energy‐transfer process in the compounds has been carefully analyzed. The visible‐emitting <bold>Tb_0.08Gd_0.92L</bold> and the near‐infrared (NIR)‐luminescent <bold>Yb_0.10Gd_0.90L</bold> show excellent optical performances and can be considered as fluorescent probes for acetone sensing based on luminescence quenching effects arising from host–guest interactions. Moreover, <bold>GdL</bold> exhibits a strong second harmonic generation (SHG) signal 6.1 times that of potassium dihydrogen phosphate (KDP) and an outstanding phase‐matchable effect. These lanthanide compounds combining fluorescent and nonlinear optical (NLO) properties could meet further requirements as multifunctional materials.</p> </abstract>
