Application

Cyclobutane-1,1-dicarboxylic acid can be used as:      
  • A reactant to synthesize lithium coordination polymer by treating with lithium carbonate.   
  • A ligand to prepare various lanthanide metal-organic frameworks (LnMOFs) via a solvothermal method. Eu+3 based MOF is applicable as a selective chemical sensor for detecting CH3OH due to its high luminescence quantum yield.

It can also be used as a starting material in the synthesis of carboplatin (cis-diammine(1,1-cyclobutanedicarboxyl-ate)platinum(II)).

Vanadium(IV) complexes are actively studied as potential candidates for molecular spin qubits operating at room temperatures. They have longer electron spin decoherence times than many other transition ions, being the key property for applications in quantum information processing. In most

The [Pd(DEEN)Cl(2)] and [Pt(DEEN)Cl(2)] complexes were synthesized and characterized where DEEN = N,N-diethylethylenediamine. The stoichiometry and stability of the complexes formed between various biologically relevant ligands (amino acids, peptides, DNA constituents and dicarboxylic acids) and [Pd(DEEN)(H(2)O)(2)](2+) were investigated at 37

Three isostructural lanthanide-based two- dimensional coordination polymers (CPs) {[Ln2(L)3(H2O)2]n⋅2n CH3OH)⋅2n H2O} (Ln=Gd(3+) (1), Tb(3+) (2), Dy(3+) (3); H2L=cyclobutane-1,1-dicarboxylic acid) were synthesized by using a low molecular weight dicarboxylate ligand and characterized. Single-crystal structure analysis showed that in complexes 1-3 lanthanide centers are
