General Description

2,6-naphthalenediphosphonic acid is a chemical compound with the molecular formula C10H8O6P2. It is a diphosphonic acid, which means it contains two phosphonic acid functional groups. 2,6-naphthalenediphosphonic acid is primarily used as a complexing agent and scale and corrosion inhibitor in industrial water treatment processes. It is also used in the production of pharmaceuticals, metal plating, and as a chelating agent in the formulation of cleaning products. 2,6-naphthalenediphosphonic acid has the ability to bind to metal ions, preventing them from forming unwanted precipitates and scale in water systems, making it an important chemical in the maintenance and preservation of water-based industrial equipment.

Rational Design of Two-Dimensional Bimetallic Wave Structures from Zigzag Chains via Site-Specific Coordination around the 2,6-Naphthalenediphosphonic Acid Motif

We report the synthesis of a novel aromatic 2,6-naphthalenediphosphonic acid (2,6-NDPA-H4) and the rational design of molecular, one-, two-, and three-dimensional structures of the resulting copper organophosphonate materials: [{Cu(terpy)}(2,6-NDPA-H3)][{Cu(terpy)}(2,6-NDPA-H3)(2,6-NDPA-H2)]·3H2O (2), [{Cu(terpy)}VO2(2,6-NDPA-H)]·H2O (4), [{Cu(terpy)}VO2(2,6-NDPA-H)] (3) and [{Cu(H2O)}(NDPA)0.5] (1). Engineering the copper coordination sphere and pH-controlled phosphonate protonation enabled the site specific dimensional evolution of CuII-organophosphonate frameworks exploiting the deprotonated phosphonate oxygen arms.

SUPERCAPACITORS COMPRISING PHOSPHONATE AND ARSONATE METAL ORGANIC FRAMEWORKS (MOFS) AS ACTIVE ELECTRODE MATERIALS

The invention relates to an electrode suitable for constructing an electrochemical double layer capacitor and/or supercapacitor and comprising as an electrode material a metal organic framework (MOF), wherein the MOF comprises an inorganic building unit comprising metal atoms selected from group 1 to group 12 elements, and functional groups of organic linkers comprising oxygen (O) and one or more atoms selected from the group comprising phosphorus (P), arsenic (As), antimony (Sb), silicon (Si), selenium (Se) and bismuth (Bi). In embodiments of the invention, the functional groups of the organic linkers are selected from the group comprising phosphonate, arsonate, phosphonic acid, phosphinic acid, arsonic acids and/or arsinic acids, monoester and/or diester forms thereof. Further, the metal atoms may be selected from the group comprising zinc (Zn), cadmium (Cd), copper (Cu), cobalt (Co), nickel (Ni), gold (Au) and silver (Ag). In further aspects the invention relates to the use of the MOF as a semiconductor and/or in semiconductor applications, and to a semiconductive device, such as a photovoltaic cell, comprising the MOF.
