“…On the basis of K SV values and the standard deviations for ten repeated luminescent measurements of blank solutions, the detection limits (3σ / K SV ) of compound 1 were also calculated. For compound 1 , CrO 4 2– , Cr 2 O 7 2– and MnO 4 – anions are efficient quenchers with detection limits of 4.12 × 10 –6 M, 1.75 × 10 –6 M, and 6.47 × 10 –7 M, respectively, which are comparable with the reported values in some compounds . However, these values are lower than some of the earlier reported values in the literature .…”

A new coordination polymer (CP), namely, [Cd(HL)(4,4Ј-bipy)] (1) (H 3 L = 4-(5-carboxy-pyridine-3-yloxy)phthalic acid, 4,4Ј-bipy = 4,4Ј-bipyridine), was synthesized employing a V-shaped asymmetric tricarboxylic acid ligand under hydrothermal condition. Single-crystal X-ray diffraction analysis indicates that compound 1 exhibits a novel three-dimensional (3D) framework with (3, 5)-connected (6 3 )(6 9 ·8) topology. Meanwhile, it shows high selectivity

“…[22] To be noted, the low stability of Cu + -and Ag + -carboxylic acid CPs based on pure soft-hard coordination bonds greatly restricts their performance and application. To solve this problem, the following strategies can usually be adopted: [23,24] (1) adding a second ligand containing soft groups into the assembled system; (2) designing a ligand containing both soft and hard groups.…”

Amphiphilic 4-(methylthio) benzoic acid (HMBA) combining soft methylthio and hard carboxylic groups was used to construct two isostructural coordination polymers of [Cu(MBA)]n (CP-1) and [Ag(MBA)]n (CP-2), and one complex of Cu2(MBA)4(CH3CN)2• CH3CN (3). This ditopic HMBA ligand realizes stable coordination of its carboxylic group with low-valent soft Cu + ion (in-situ reduction from Cu 2+ ) under the assistance of methylthio groups, forming CPs of CP-1 and CP-2. Meanwhile, based on the theory of hard and soft acid and base (HSAB), harder Cu 2+ ions (in-situ oxidation from Cu + ) only coordinate to carboxylic groups, affording a paddle-wheel dinuclear complex 3. These two CPs were also taken for luminescent researches in solid state. CP-1 exhibits single-peak emission at 540 nm while CP-2 emits both at 499 and 528 nm with green luminescence. The emissions of CP-1 and CP-2 are both attributed to 3 MLCT (triplet metal-to-ligand charge transfer) excitation state.

“…For instance, an LMOFs assembled from Ag 12 cluster cores demonstrate fascinating oxygen sensing . The Ag-LMOF derived from 2,5-dichloroterephthalic acid and 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene shows a selective luminescence response to Cr 2 O 7 2– ions . A riboflavin-functionalized cyanobenzoate Ag-LMOF was used for the emission sensing of melamine and acetoguanamine .…”

A series of isoreticular Ag(I) luminescent metal− organic frameworks (LMOFs), {[Ag 2 L 2 (CH 3 CN) 2 ](X) 2 } n (X = ClO 4 , OTf, and BF 4 ), has been designed, exploiting diphenyl(2pyrazyl)phosphine (L) as a multidentate linker. At ambient temperature, these compounds emit a bright long-lived phosphorescence (λ em = 545−555 nm) with a quantum efficiency as high as 22%, which is the highest value for phosphorescent Ag-LMOFs. The prepared LMOFs also exhibit pronounced thermochromic luminescence, reversibly changing their emission color in the 300− 77 K range. These LMOFs also demonstrate prominent solvatoand vapochromic luminescence, which manifest as a reversible change in the emission properties during the removal and recovery of the coordinated and guest MeCN molecules, respectively. Moreover, we have discovered a reversible solvent-driven 3D-to-0D transformation of the framework {[Ag 2 L 2 (CH 3 CN) 2 ](ClO 4 ) 2 } n into a brightly emissive complex [Ag 4 L 4 (ClO 4 ) 4 ]. To the best of our knowledge, the compounds obtained are the first Ag-LMOFs that exhibit thermo-, solvato-, and vapochromic luminescence.
