TL;DR: It is shown that the chemisorption of gaseous HCl molecules by a non-porous one-dimensional coordination polymer instigates drastic modifications in the magnetic properties of the material.
Abstract: Tuning the properties of responsive materials by applying an external stimulus could lead to their application as chemical switches or molecular sensors. Coronado et al. develop a non-porous one-dimensional coordination polymer, the magnetic properties of which undergo drastic changes on chemisorption of gaseous HCl.

TL;DR: A novel highly semiconducting 1D coordination polymer architecture obtained by the reaction of a Cu(II) salt with 2,2'-dipyridyldisulfide under microwave solvothermal conditions suggests new perspectives for the use of coordination polymers as electrical conducting materials.
Abstract: We report on a novel highly semiconducting 1D coordination polymer architecture obtained by the reaction of a CuII salt with 2,2′-dipyridyldisulfide under microwave solvothermal conditions. This reaction proceeds with an unusual C−S and S−S bond cleavage of the 2,2′-dipyridyldisulfide ligand. The unprecedented architecture of this coordination polymer consists of a 1D chain formed by the assembling of Cu9 cluster cages. The electrical conductivity behavior of this novel material suggests new perspectives for the use of coordination polymers as electrical conducting materials.

TL;DR: The design and synthesis of a responsive lanthanide coordination polymer (LCP) for hydrogen sulfide (H2S) is reported, utilizing self-assembling of biomolecule nucleotide with luminescent terbium ion (Tb(3+)) and sensitizing silver ion (Ag(+)) in aqueous solution.
Abstract: Metal organic coordination polymers have received great attention because of their flexible compositions and architecture. Here, we report the design and synthesis of a responsive lanthanide coordination polymer (LCP) for hydrogen sulfide (H2S), utilizing self-assembling of biomolecule nucleotide with luminescent terbium ion (Tb3+) and sensitizing silver ion (Ag+) in aqueous solution. LCP is highly fluorescent due to the inclusion of Ag+ ions, which sensitized the fluorescence of Tb3+ ions. H2S can strongly quench the fluorescence of LCP through its high affinity for Ag+ ions. Such configurated LCP material from initial building blocks showed high sensitivity and selectivity for H2S and was applied to the determination of H2S in human serum. LCP with Tb3+ ions also has a long fluorescence lifetime, which allows for time-resolved fluorescence assays, possessing particular advantages to probing H2S in biological systems with autofluorescence.

TL;DR: The coordination polymer as mentioned in this paper is a polyknotted structure in which each Cd(II) center is coordinated by three pyridyl N-donors arranged in an approximate T-shaped geometry to form a ladder motif.
Abstract: The coordination polymer {[Cd2(4,4‘-pytz)3(μ-NO3)(NO3)3(MeOH)]}∞, 1, displays a unique polyknotted structure in which each Cd(II) center is coordinated by three pyridyl N-donors arranged in an approximate T-shaped geometry to form a ladder motif. Within this structure, each ladder is interpenetrated perpendicularly by two other ladders. Significantly, each of the Cd(II) centers at the intersections of one ladder is bridged by a coordinated NO3- anion to a Cd(II) center located at the corner of a square section of one of the perpendicularly interpenetrated ladders. Thus, all the ladders are linked together to give a three-dimensional polymer where the overall architecture is constructed of one molecule in a fused “polyknot”.
