nanoparticles of coordination polymer [co2(pydc)2(h2o)6]n.2n h2o [h2pydc = pyridine-2,5-dicarboxylic acid] have been synthesized by sonochemical method and characterized by elemental analysis, infrared spectroscopy, powder x-ray diffraction, scanning electron microscopy, dls particle size analysis and tga/dta. the structure of single crystalline coordination polymer developed from nanosized coo...
One-dimensional coordination polymers (1D-CPs) tend either to dissociate into constitutive ligands and metals readily in solution, or to aggregate randomly and amorphously, which prevents them from widespread application. In the present research, 1D-CPs comprising bridging dipyrrin ligands and divalent metal ions (Zn2+, Ni2+, and Cu2+) are synthesized. A liquid/liquid interfacial reaction gives...
Self-assembly of Ag2O, 1,4-bis(pyrid-4-yl)benzene (dpb) and 1,3-benzenedicarboxylic acid (H2bdc) resulted in a one-dimensional mixed-ligand Ag(I) coordination polymer [Ag2(dpb)2(bdc)·9H2O]n (1), in which infinite 1D T4(0)A(0)6(0) water tapes and discrete water hexamers were simultaneously encapsulated. Chair-like water hexamers and D2h water tetramers with two dangling water molecules were alte...
The reaction of the phosphate monoester {(ArO)PO(OH)2} (Ar = 2,6-i-Pr2C6H3) with BiPh3 in a 1 : 1 ratio in refluxing toluene afforded a tetradecabismuth-oxo-phosphate cage [{(ArO)PO3}10{(ArO)PO2OH}2(Bi14O10)·2(CH3OH)]·3C6H12·3CH3OH·2H2O (Ar = 2,6-i-Pr2C6H3) (1). On the other hand the reaction of the phosphate diester {((t)BuO)2PO(OH)} with BiPh3 in a 1 : 1 ratio at room temperature in ethanol a...
One new coordination polymer, namely, [Cd3(H2L)3(Pza)2(H2O)2]n (1) was synthesized by the reaction of Cd(NO3)2·4H2O with 1,4-di(1H-imidazol-4-yl)benzene (H2L) and 3,5-pyrazoledicarboxylic acid (H3pza) and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis, and powder X-ray diffraction (PXRD). The H3pza ligand was completely deprotonated to pza3−, which bridge...
The preparation and characterization of a novel hybrid material based on the combination of a 2D-layered double hydroxide (LDH) nanosheets and a 1D-coordination polymer (1D-CP) has been achieved through a simple mixture of suspensions of both building blocks via an exfoliation/restacking approach. The hybrid material has been thoroughly characterized demonstrating that the 1D-CP moieties are in...
The reaction of AgNO3 with 1-(4-pyridylmethyl)-1H-benzotriazole (4-pbt) afforded a photoluminescent onedimensional (1D) double-helical coordination polymer {[Ag(4-pbt)](NO3)} (1) formed by interchain C-H supramolecular interactions of the single-helical chains. Adjacent 1D double-helical motifs aforementioned were assembled into different two-dimensional (2D) sheets from the different crystallo...
Three mixed-ligand coordination polymers, [Cu(oda)(2,2'-bipy)](2) (1), Ni(2)(oda)(2)(4,4'-bipy)·DMF (2), and [{Ni(oda)(H(2)O)(2)}(2)(μ-4,4'-bipy)]·2H(2)O (3) were synthesized and characterized. Complex 1 features a 1D chain via intermolecular π-π interactions. Complex 2 is a novel 3D microporous coordination polymer with 1D polarized channels. Complex 3 forms a 3D network via extensive hydrogen...
Novel diamino and azamacrocycle functionalized porphyrins were efficiently synthesized by palladium-catalyzed amination of mono- and bis(meso-(bromophenyl))porphyrins. The optimization of reaction conditions allowed us to achieve high yields of products with substrates of different types. Supramolecular utility of the thus obtained aminoporphyrins was shown by investigations of processes of coo...
