Tetrakis(triazolylmethyl)ethylenediamine, which is a class of tetrakis(2‐pyridylmethyl)ethylenediamine (TPEN) analogue, is synthesized by a quadruple click reaction of tetrapropargylated ethylenediamine and four equivalents of alkyl azide. The obtained compound efficiently extracted the soft metal cadmium(II) ions by solvent extraction . It is also found that an N ‐isopropylacryl amide (NIPA) gel using the triazole ethylenediamine as a cross‐linker exhibits a temperature‐dependent extraction performance.
