Design and synthesis of coordination polymers with Cu(ii) and heterocyclic N-oxides

Abstract

The relations of coordination network connectivity with coordination properties of heterocyclic N-oxides, Cu(I,II), and co-ligands were discussed based on the comparative analysis of 623 structures extracted from the Cambridge Structural...

Tuning ESIPT-coupled luminescence by expanding π-conjugation of a proton acceptor moiety in ESIPT-capable zinc(ii) complexes with 1-hydroxy-1H-imidazole-based ligands

“…[56][57][58][59][60][61][62][63][64][65][66][67][68] Although the molecules of ESIPT-fluorophores can bind metal ions (which is used for the detection of metals), this phenomenon is typically coupled with their deprotonation and the disappearance of ESIPT in the metal complex molecules (Scheme 2, top). [69][70][71][72][73][74][75][76] Nevertheless, the purposeful design of specific sites for metal coordination in the molecules of ESIPT-fluorophores paves the way toward metal ion binding without the deprotonation of ESIPT-fluorophores (Scheme 2, bottom). The ligands capable of demonstrating ESIPT in metal complexes can be referred to as ESIPT-capable ligands or ESIPT-ligands.…”

A Zn(II) Coordination Polymer for Fluorescent Turn-Off Selective Sensing of Heavy Metal Cation and Toxic Inorganic Anions

“…It has been well documented that due to their fast response, high sensitivity and naked eye monitoring, fluorescent CPs can be one type of good chemical sensor for detecting analytes through fluorescence quenching, enhancement or shift [ 13 , 14 , 15 , 16 ]. Reasonable selection of metal nodes and organic linkers is of great significance for the construction of fluorescent CPs [ 17 , 18 , 19 ]. It was found that fluorescent CPs constructed by heterocyclic carboxylate ligands and d 10 metal centers show excellent photoluminescence performance [ 20 , 21 ].…”

Design and synthesis of copper(ii) malonates with N,N′-containing linkers

“…Some examples of reticular chemistry approaches to the design of coordination polymers with novel topologies by using polytopic ligands with a controlled coordination mode and metal ions with a controlled coordination figure are described in ref. 10-17. Also, some examples of expert systems to predict 2D and 3D coordination polymers for copper(I,II) heterocyclic N-oxides, 18 zinc(II) malonates, 8,9 metal 4,5,6-trihydroxyisophthalates, 19 cyanides, 20 and polycyanides 21 have been published. Besides, a topological approach for the synthesis of acentric solids based on hydroxyisophthalates for applications in non-linear optics to proton conductors and fluorescent materials was also recently tested.…”
