  • Patent number: 12055496
    Abstract: Embodiments of the present disclosure pertain to methods of monitoring an environment for the presence of a solvent by: (i) exposing the environment to a luminescent compound, where the relative luminescence emission intensity of the luminescent compound changes upon interaction with the solvent; and (ii) monitoring a change in the relative luminescence emission intensity of the luminescent compound, where the absence of the change indicates the absence of the solvent from the environment, and where the presence of the change indicates the presence of the solvent in the environment. The luminescent compounds include a phosphorous atom with one or more carboxyl groups, where the carboxyl groups are coordinated with one or more metallic ions (e.g., lanthanide ions and yttrium ions). The present disclosure also pertains to sensors for monitoring an environment for the presence of a solvent, where the sensors include one or more of the aforementioned luminescent compounds.

  • Publication number: 20220168689
    Abstract: Embodiments of the present disclosure pertain to methods of sorption of H2O from an environment by associating the environment with a porous material such that the association results in the sorption of H2O to the porous material. The porous material includes a (M)-2,4-pyridinedicarboxylic acid coordination polymer, where M is a divalent metal ion selected from the group consisting of Mn, Fe, Co, Ni, Mg, and combinations thereof. The coordination polymer has a one-dimensional pore structure and shows reversible soft-crystal behavior. The porous material may be a Mg(II) 2,4-pyridinedicarboxylic acid coordination polymer (i.e., Mg-CUK-1). The methods of the present disclosure may also include one or more steps of releasing the sorbed H2O from the porous material and reusing the porous material after the releasing step for sorption of additional H2O from the environment.
