“…Multicarboxylic acids, especially dicarboxylic acid, have been extensively used to construct metal‐organic frameworks. Benzenedicarboxylic acid, 2, 6‐naphthalene‐dicarboxylic acid and 4, 4′‐diphenyldicarboxylic acid have been successfully introduced in the construction of complexes with novel topologies and multiple functions,24–28 which can be assigned to their conformation rigidity and versatile coordination modes. 3‐(4‐Carboxyphenyl) propionic acid (H 2 cpp) has two asymmetric carboxylate groups, in which the longer carboxylate group –CH 2 CH 2 COOH is flexible and able to bend.…”

Two new nickel(II) complexes, [Ni(4,4Ј-bpy)(H 2 O) 4 ] n · n(cpp)·0.5nH 2 O (1) and [Ni(cpp)(4,4Ј-bpy)(H 2 O) 2 ] n (2) [4,4Ј-bpy = 4,4Ј-bipyridine, H 2 cpp = 3-(4-carboxyphenyl)propionic acid] were synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy, and thermal analysis. In complex 1, Ni II ions are bridged by 4,4Ј-bpy into 1D chains, and cpp ligands are

“…Both Me 2 NH + 2 and Et 2 NH + 2 directly derived from DMF or DEF solvents may not be suitable for the generation of stable framework structures. Me 2 NH + 2 and Et 2 NH + 2 ions are thought to be generated by thermal decomposition of DMF or DEF, respectively (Gu et al, 2012). Contrarily, as tetraethylammonium bromide (TEAB) was added into the reaction mixture of DEF, good red block crystals were obtained as shown in Figure 2c.…”

“…Additionally, there should be a counter-cation near each [In(O 2 CR) 4 ] − node because of charge matching. There are many examples of 3D In-MOFs solely derived from ditopic, tritopic, tetratopic, and pentatopic carboxylate-based bridging ligands (Sun et al, 2002;Lin et al, 2007Lin et al, , 2012Huh et al, 2009;Gu et al, 2012;Yu et al, 2012;Zheng et al, 2013;Cho et al, 2014;Huang et al, 2014;Johnson et al, 2014;Wang et al, 2014;Grigoropoulos et al, 2016;Li et al, 2016;Aguirre-Díaz et al, 2017;Zhao et al, 2017;Yang et al, 2019). The most common counter-cations are either Me 2 NH + 2 or Et 2 NH + 2 which can be in-situ generated from the solvents: N,Ndimethylformamide (DMF) or N,N-diethylformamide (DEF).…”

Gas Sorption Properties of a New Three-Dimensional In-ABDC MOF With a Diamond Net

The pseudotetrahedral node, [In(O 2 CR) 4 ] − , often found in In III-based metal-organic frameworks (MOFs) without a cluster-based secondary building unit (SBU) is a negatively charged center due to charge mismatch between an 8-coordinate In III ion and four anionic carboxylate bridging ligands. Thus, In-MOFs with this pseudotetrahedral node tend to bear a counter-cation near each In III center in the frameworks. Generally, dialkylammonium-based cations such as Me 2 NH + 2 and Et 2 NH + 2 directly derived from N,N-dimethylformamide (DMF) or N,N-diethylformamide (DEF) solvents during MOF formation reactions play a significant role to form a stable framework through charge matching. If these cations thermally derived from DMF or DEF were not suitable for crystal growth of In-MOFs, it becomes very challenging to obtain high quality single crystals for X-ray structure determination of the frameworks. In this context, high quality crystals of In-ABDC MOF were not easily prepared from a ditopic azobenzene-4,4'-dicarboxylic acid (H 2 ABDC) through a thermal reaction in DMF or DEF. We successfully overcome this problem by employing a room-temperature ionic liquid, 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM][BF 4 ]), and the resulting three-dimensional (3D) In-ABDC MOF, [EMIM][In(ABDC) 2 ]•DEF•H 2 O (I), was structurally characterized by X-ray diffraction. The 3D framework indicates a 4-connected uninodal net with Schläfli symbol of 6 6 (dia). The gas sorption properties of solvent-free I were also investigated in detail.

“…Such difference is explained by the fact that in the case of the two-chain DNA intercalation of the dye occurs between the nucleic bases, preventing the formation of aggregates, whereas the AO in the complexes with RNA is in an aggregated state. Recently it was also shown that the sorption of AO can be used to determine the sorption characteristics of porous CPs [21][22][23][24], although a detailed study of the luminescent characteristics of the obtained materials has not been undertaken.…”

Effect of Aggregation of Acridine Orange on the Luminescent Characteristics of Its Composites with a Zinc-Containing Coordination Polymer

et al. 2015

acridine orange depends on the ratio of the amounts of aggregated and isolated molecules of the dye, which in turn depends on the conditions under which the composites are produced. In all cases energy is transferred from the coordinated polymer to the dye, leading to bimodal luminescence in the composites.The coordination polymers (CPs) formed by metal ions and polydentate organic bridging ligands (linkers) have attracted much interest in recent decades on account of their specific sorption, magnetic, optical, and catalytic characteristics and their associated potential use for possible applications in various fields [1][2][3][4]. The almost unlimited set of metal-containing units and bridging ligands that can be used today for the construction of CPs opens up wide possibilities for varying the properties of the materials. On account of the thermal stability, kinetic inertness, and tetragonal structure of the coordination polyhedra [5] the complexes of metals with tetradentate aza macrocyclic ligands present a promising class of metal-containing building blocks that retain their identity in the processes involved in the formation of coordination-polymer chains and are characterized by predictable linear bimodality arising from the presence of two vacant positions in the coordination sphere of the metal. At the present time a considerable number of CPs formed by aza macrocyclic complexes have been described, and most of them contain aromatic carboxylates as linkers [6,7]. As a rule these linkers only play an architectural role in the spatial organization of the metal-containing building blocks in the polymeric networks without involvement of their inner properties in the functional behavior of the materials.One of the important factors that make it possible to use the properties of bridging aromatic carboxylates for practical purposes is their luminescent behavior. In particular, it was established that CPs formed by the ions of non-transition metals or 0040-5760/15/5104-0259 ©2015 Springer Science+Business Media New York 259 ________ 1 L.
