TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The metal clusters are selected from metal clusters of formula M'mX'n (preferably Zn4O clusters). The metal clusters comprises at least one non-linking ligand. The non-linking ligand is selected from O2-, sulfate, nitrate, nitrite, sulfite, bisulfite, phosphate, hydrogen phosphate, dihydrogen phosphate, diphosphate, triphosphate, phosphite, chloride, chlorate, bromide, bromate, iodide, iodate, carbonate, bicarbonate, sulfides, hydrogen sulphate, selenide, selenate, hydrogen selenate, telluride, tellurate, hydrogen tellurate, nitride, phosphide, arsenide, arsenate, hydrogen arsenate, dihydrogen arsenate, antimonide, antimonate, hydrogen antimonate, dihydrogen antimonate, fluoride, boride, borate, hydrogen borate, perchlorate, chlorite, hypochlorite, perbromate, bromite, hypobromite, periodate, iodite and/or hypoiodite. The dopant is an electropositive dopant and is selected from elements from Groups 1 through 13, lanthanides or actinides; or alkali dopant (preferably lithium). The ratio of aromatic carbon atoms to dopant atoms is 4:1 to 7:1 (preferably 5:1 to 6:1). The dopant is present in the metal-organic framework in an amount of 2.5-7.2 (preferably 2.63-7.01) wt.%. The multi-dentate ligand is selected from 39 optionally substituted ligands of formula (I) to (V). When the metal clusters comprises Zn4O(CO2)6 clusters, and the multi-dentate linking ligand is the ligand of formula (V).M'=Li+, Na+, K+, Rb+, Be+, Mg2+, Ca2+, Sr2+, Ba2+, Sc3+, Y3+, Ti4+, Zr4+, Hf+, V4+, V3+, V2+, Nb3+, Ta3+, Cr3+, Mo3+, W3+, Mn3+, Mn2+, Re3+, Re2+, Fe3+, Fe2+, Ru3+, Ru2+, Os3+, Os2+, Co3+, Co2+, Rh2+, Rh+, Ir2+, Ir+, Ni2+, Ni+, Pd2+, Pd+, Pt2+, Pt+, Cu2+, Cu+, Ag+, Au+, Zn2+, Cd2+, Hg2+, Al3+, Ga3+, In3+, Tl3+, Si4+, Si2+, Si2+, Ge4+, Ge2+, Sn4+, Sn2+, Pb4+, Pb2+, As5+, As3+, As+, Sb5+, Sb3+, Sb+, Bi5+, Bi3+ and/or Bi+;X=anions of non-metal atoms from Groups 14 through 17 (preferably anions of O, N or S);m=1-10;n=charge balance the metal cluster;M1=a metal atom;R1=1-10C alkyl;X1=H, -NHR1, -N(R1)2, halides, 1-10C alkyl, 6-18C aryl, 6-18C aralkyl, -NH2, alkenyl, alkynyl, -O-alkyl, -NH(aryl), cycloalkyl, cycloalkenyl, cycloalkynyl, -(CO)R1, -(S2)R1, -(CO2)R2, -SH, -S(alkyl), -SO3H, -SO3-(M1)+, -COOH, -COO-(M1)+, -PO3H2, -PO3H-(M1)+, -PO32-(M1)2+, -NO2, -CO2H, silyl derivatives, borane derivatives, ferrocenes or metallocenes;X2=amines, aromatic amines, pyridine, pyrimidine like five and six membered rings, halides, halogen substituted by R1 groups (-R1X2), alcohols, thiols, sulfonates, nitro groups, phosphates, epoxides, alkanes, alkenes, alkynes, aldehydes, ketones, esters, carboxylic acids, cycloalkanes, cycloalkenes, cycloalkynes, silyl derivatives, borane derivatives, ferrocenes or other metallocenes.
