- wherein:
- q is 1 or 2,
- Aq+ represents a cation selected from the group consisting of alkali metal cations where q=1, ½ alkaline earth cations where q=2, and ammonium ions where q=1,
- Ms+ represents an aluminum ion, a transition metal ion, or a lanthanide metal ion,
- s is a number from 1 to 5,
- L represents a ligand of the formula (II),
- wherein:
- each R1 and R2 independently of each other is selected from the group consisting of H, unsubstituted or substituted, linear or branched C1-20 alkyl, unsubstituted or substituted, linear or branched C1-20 heteroalkyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, unsubstituted or substituted, linear or branched C2-20 alkenyl, unsubstituted or substituted, linear or branched C2-20 heteroalkenyl, unsubstituted or substituted, linear or branched C2-20 alkinyl, unsubstituted or substituted, linear or branched alkylaryl, and unsubstituted or substituted, linear or branched alkylheteroaryl, and
- each R3 independently of each other represents CH2COOH or CH2COO−,
- n is 0 or 1,
- Xo− represents an anion selected from the group consisting of F−, Cl−, Br−, I−, OH−, HSO3−, SO32−, SO42−, HSO4−, NO2−, NO3−, PO43−, HPO42−, H2PO4−, BF4−, PF6−, ClO4−, acetate, citrate, formate, glutarate, lactate, malate, malonate, oxalate, pyruvate, tartrate, methane sulfonate, methyl sulfate, p-toluene sulfate, and succinate,
- m is a number from 0 to 5,
- is a number from 1 to 3, and
- p and r are independently of each other a number from greater than 0 to 6, such that the sum of s and the product of p and q is equal to the sum of m and the product of r and o, and further such that the charge of formula (II) resulting from the radicals R1, R2 and R3 is neutral or negative.
