High-Throughput Synthesis of Pillared-Layered Magnesium Tetraphosphonate Coordination Polymers: Framework Interconversions and Proton Conductivity Studies
(MDPI, www.mdpi.com/journal/inorganics, 2018-09-11)
Novel pillared-layered framework materials were synthesized by high-throughput
or microwave-assisted methodology that contain Mg2+ and the zwitterionic linker HDTMP
(hexamethylenediamine-N,N,N0,N0-tetrakis(methylenephosphonic ...
Structural Variability in Multifunctional Metal Xylenediaminetetraphosphonate Hybrids
(American Chemical Society, 2013-07-24)
Two new families of divalent metal hybrid derivatives from the aromatic tetraphosphonic acids 1,4- and 1,3-bis(aminomethyl)benzene-N,N′-bis(methylenephosphonic acid), (H2O3PCH2)2−N−CH2C6H4CH2−N(CH2PO3H2)2 (designated herein ...
Tuning Proton Conductivity in Alkali Metal Phosphonocarboxylates by Cation Size-Induced and Water-Facilitated Proton Transfer Pathways
(American Chemical Society, 2014-12-20)
The structural and functional chemistry of a family of alkali-metal ions with racemic R,S-hydroxyphosphonoacetate (M-HPAA; M = Li, Na, K, Cs) are reported. Crystal structures were determined by X-ray data (Li+, powder ...
Structural variability in M2+ 2-hydroxyphosphonoacetate moderate proton conductors
(De Gruyter, 2017)
The structural variability of two series of Mg2+- and Zn2+- 2-hydroxyphosphonoacetates have been
studied in the range of 25–80 °C and 95 % relative humidity in order to correlate the structure with the
proton conductivity ...
Guest Molecule-Responsive Functional Calcium Phosphonate Frameworks for Tuned Proton Conductivity
(American Chemical Society, 2014-03-18)
We report the synthesis, structural characterization, and functionality of an open-framework hybrid that combines Ca2+ ions and the rigid polyfunctional ligand 5-(dihydroxyphosphoryl) isophthalic acid (PiPhtA). Ca-PiPhtA-I ...
High Proton Conductivity in a Flexible, Cross-Linked, Ultramicroporous Magnesium Tetraphosphonate Hybrid Framework
(American Chemical Society, 2012-07-03)
Multifunctional materials, especially those combining two or more properties of interest, are attracting immense attention due to their potential applications. MOFs, metal organic frameworks, can be regarded as multifunctional ...
Multifunctional lanthanum tetraphosphonates: Flexible, ultramicroporous and proton-conducting hybrid frameworks
(The Royal Society of Chemistry, 2012)
A new flexible ultramicroporous solid, La(H5DTMP)·7H2O (1), has been crystallized at room temperature using the tetraphosphonic acid H8DTMP, hexamethylenediamine-N,N,N′,N′-tetrakis(methylenephosphonic acid). Its crystal ...
Photodegradation of Phenol over a Hybrid Organo-Inorganic Material: Iron(II) Hydroxyphosphonoacetate
(American Chemical Society, 2012-06-20)
Water treatment is a hot topic, and it will become much more important in the decades ahead. Advanced oxidation processes are being increasingly used for organic contaminant removal, for example using photo-Fenton reactions. ...
