Application

2,5-Thiophenedicarboxylic acid is a versatile compound primarily used as a thiophene-based linker in the production of magnesium coordination networks. It serves as a crucial precursor in the synthesis of 2,5-bis-benzoxazoyl-thiophene (EBF) and is employed in creating innovative materials including new cobalt(II) thiophenedicarboxylate coordination polymers. This compound also plays a vital role in the development of novel mesogenic thiophene-based supramolecular liquid crystals. Additionally, it is instrumental in synthesizing unique coordination polymers like {[Ln2(2,5-tdc)3(dmso)2]H2O}n, where Ln represents Tb(III) and Dy(III), illustrating its broad application in advanced material science.
