Exploring porosity in a flexible 3D organic-inorganic {ZnII3(4DPNDI)[W(CN)]} coordination network.

A 2D cyanido-bridged architecture Zn-[W(CN)] is smoothly pillared by ,'-di-(4-pyridyl)-1,4,5,8-naphthalenetetracarboxydiimide (4DPNDI) into 3D hybrid porous coordination polymer (PCP) {ZnII3(DMA)[W(CN)](4DPNDI)·8DMA}. It shows significant uptake of HO, MeOH or CHCl vapours with easy regeneration to the native form, and breathing-type CO adsorption contrasting non-porosity towards N, providing a new example of a highly flexible porous material.

Influence of O-H⋅⋅⋅Pt interactions on photoluminescent response in the (EtN){[Pt(bph)(CN)][phenylene-1,4-diresorcinol]} framework.

Tunable photoluminescence (PL) is one of the hot topics in current materials science, and research performed on the molecular phases is at the forefront of this field. We present the new (EtN)[Pt(bph)(CN)]⋅rez3⋅/HO (Pt2rez3) (bph=biphenyl-2,2'-diyl; rez3=3,3",5,5"-tetrahydroxy-1,1':4',1"-terphenyl, phenylene-1,4-diresorcinol coformer, a linear quaternary hydrogen bond donor) co-crystal salt based on the recently appointed promising [Pt(bph)(CN)] luminophore. Within the extended hydrogen-bonded subnetwork [Pt(bph)(CN)] complexes and rez3 coformer molecules form two types of contacts: the O-H⋅⋅⋅N ones in the equatorial plane of the complex and non-typical O-H⋅⋅⋅Pt ones along its axial direction.

Nonlinear and Emissive {[M(CN)]···Polyresorcinol} (M = Fe, Co, Cr) Cocrystals Exhibiting an Ultralow Frequency Raman Response.

Optically active functional noncentrosymmetric architectures might be achieved through the combination of molecules with inscribed optical responses and species of dedicated tectonic character. Herein, we present the new series of noncentrosymmetric cocrystal salt solvates (PPh)[M(CN)](L)·solv (M = Cr(III), Fe(III), Co(III); L = polyresorcinol coformers, multiple hydrogen bond donors: 3,3',5,5'-tetrahydroxy-1,19-biphenyl, DiR, = 2, or 5'-(3,5-dihydroxyphenyl)-3,3″,5,5″-tetrahydroxy-1,19:3',1″-terphenyl, TriRB, = 1) denoted as and , respectively. The hydrogen-bonded subnetworks {[M(CN)];L} of , , or topology are formed through structural matching between building blocks within supramolecular -bis(chelate)-like {[M(CN)];(L)(L)} or tris(chelate)-like {[M(CN)];(L)} fragments.

Supramolecular -"Bis(Chelation)" of [M(CN)] (M = Cr, Fe, Co) by Phloroglucinol (HPG).

Studies on molecular co-crystal type materials are important in the design and preparation of easy-to-absorb drugs, non-centrosymmetric, and chiral crystals for optical performance, liquid crystals, or plastic phases. From a fundamental point of view, such studies also provide useful information on various supramolecular synthons and molecular ordering, including metric parameters, molecular matching, energetical hierarchy, and combinatorial potential, appealing to the rational design of functional materials through structure-properties-application schemes. Co-crystal salts involving anionic -metallate coordination complexes are moderately explored (compared to the generality of co-crystals), and in this context, we present a new series of isomorphous co-crystalline salts (PPh)[M(CN)](HPG)·2MeCN (M = Cr, ; Fe, ; Co ; HPG = phloroglucinol, 1,3,5-trihydroxobenzene).

Exploring the structure-property schemes in anion-π systems of d-block metalates.

Anion-π based compounds, materials, and processes have gained significant interest due to the diversity of their aesthetic non-covalent synthons, and thanks to their significance in biological systems, catalytic processes, anion binding and sensing, or the supramolecular organization of hierarchical architectures. While systems based on typical inorganic anions or organic residues have been widely reviewed in recent years, those involving anionic d metal comlexes as the main components have been treated with a rather secondary interest. However, actively exploring the new systems of the latter type we have recognized systematic advances in the field.

Application of bioorthogonal hetero-Diels-Alder cycloaddition of 5-arylidene derivatives of 1,3-dimethylbarbituric acid and vinyl thioether for imaging inside living cells.

New bioorthogonal cycloaddition of 5-arylidene derivatives of 1,3-dimethylbarbituric acid as 1-oxa-1,3-butadienes and vinyl thioether as a dienophile has been applied to imaging inside living cells. The reaction is high yielding, selective, and fast in aqueous media. The proposed 1-oxa-1,3-butadiene derivative conjugated to a FITC fluorochrome selectively and rapidly labels the cancer cells pretreated with the dienophile-taxol.
