Enhanced stability and colorimetric detection on Ag(i) ions of a methylthio-functionalized Zn(ii) metal–organic framework

Abstract

A tripodal linker with six pendant methylthio (-SCH3) groups was crystallized with Zn(II) ions to provide metal-organic framework (MOF) crystals, namely NOTT-6SMe-Zn, bearing three kinds of cage-like pores. NOTT-6SMe-Zn gives...

A 2-fold interpenetrated zinc–organic framework with Lewis basic triazole sites: luminescence sensing of Fe3+ and Cr2O72−, and warm white-light emission by encapsulated Ln3+ ions

“…The Zn 2+ ion with a d 10 configuration is hard to be oxidized or reduced; therefore the luminescence of compound 1 could originate from the intraligand luminescence emission. 27 The shift of the emission peaks is probably ascribed to the enhancement of skeleton rigidity by the coordination interaction of the ligands to Zn 2+ . 28,29 It is worth noting that the maximum emission peak of compound 1 suspension in DMF solvent exhibits a blue shift (370 nm excited on 290 nm) compared to that of the solid sample (Fig.…”

Anion-Induced Structural Transformation of a Cage-Based Metal–Organic Framework

“…As a kind of hybrid functional materials, metal–organic frameworks have received increasing attention in catalysis, − luminescent detection, − ion-exchange, , gas storage, separation, − and other application fields − over a long period in virtue of their high specific surface areas, permanent porosity, functional porous surface, and excellent thermal stability. In particular, the abundant and accessible pores endow the materials with enough accommodation space to further expand their applications in various fields.…”

MOF-based colorimetric sensor for rapid and visual readout of trace acetylene

“…[1][2][3][4][5] Particularly, MOF colorimetric sensors, which are based on their color change in response to targeted substances, feature operation convenience and the elimination of any instruments. [6][7][8] To date, the reported examples are usually designed through two strategies. One is the alternation of the metal coordination geometry by analytes.…”
