“…The relative strong acidity of carboxylic functions in pyromellitic acid is not favorable for complexation of the ura-nium cation in DMF. Then, a small amount of water could favor the hydrolysis of DMF [35,36] under solvothermal conditions, [37][38][39][40] and the production of dimethylamine, [41] which is required to fully deprotonate pyromellitic acid. Such a reaction is not required with carboxylic acids with lower pK a values, since dimethylamine produced by thermal decomposition of DMF is sufficient to generate the reactive carboxylate function.…”

Three new coordination polymers bearing tetravalent uranium have been isolated with the O‐donor ligands such as isophthalate (1,3‐bdc) or pyromellitate (btec). The compounds 1 and 3 have been solvothermaly synthesized in N,N‐dimethylformamide (DMF). The crystal structure of U(1,3‐bdc)2(DMF) (1) is built up from discrete tricapped trigonal‐primastic UO9 units, for which one carbonyl oxygen atom from DMF is bound to uranium. The connection of the UO9 units with the isophthalate linkers occurs in a chelating and bidentate fashion and gives rise to the formation of a 3D framework, delimiting narrow channels running along the [101] direction. Upon heating, the DMF molecules are removed, generating the second phase U(1,3‐bdc)2 (2) compound, closely related to 1. Indeed, the coordination environment of uranium is reduced to eight with a distorted square‐antiprismatic geometry. This transition induces the relative shrinkage of the network (ΔV = 23 %). The structure of the compound U(btec)(DMF)2 (3) also exhibits a 3D framework composed of an isolated bicapped square‐antiprismatic UO10 unit, for which two carbonyl oxygen atoms from DMF are bonded to uranium. Pyromellitate ensures the connection of the UO10 units through the carboxylate arms in a chelating mode. This results in the formation of a network with diamond‐shaped channels, developed along the c axis and encapsulating the DMF molecules. In contrast to 1, no stable phase is observed upon removing the DMF species by heating.

“…It is worth to illustrate that the introduction of the NMe2 functionality by SNAr substitution, occurred unexpectedly from DMF decomposition. Indeed, some literature reports 47,48 described that under specific reaction conditions DMF could decompose providing a source of-NMe2 group, which in our case would be the responsible of the second substitution on the naphthalene core.…”

A reversible fluorescent probe L based on rhodamine 6G was synthesized for the optical detection of Fe 3+ in water. This probe displayed a favorable selectivity for Fe 3+ with a 1:1 stoichiometry. It displays a fluorescence turn-on response in the process of rhodamine ring-opening with Fe 3+ and a fluorescence turn-off response when added Na4P2O7 to the L-Fe 3+ complex, respectively. The association constant between the probe and Fe 3+ was detected to be 3.5×10 4 M -1 , and the corresponding detection limit was calculated to be 1.9×10 -8 M according to fluorescence titration analysis. Furthermore, Bioimaging investigations indicatated that this probe was cell permeable and suitable for monitoring interacellular Fe 3+ in living cells by confocal microscopy.
