“…All manipulations were performed under an argon atmosphere with the use of standard Schlenk techniques unless otherwise stated. The ligand abpt 45 and metal organic fragment CpMe n (dppe)M II CN 46–48 were prepared according to published papers. All other chemical solvents were available commercially at reagent grade and used without further purification.…”

The multistep synthesis of a versatile new 4‐substituted 3,5‐bis(2‐pyridyl)‐1,2,4‐triazole (Rdpt) ligand, 4‐[4‐(2‐aminomethyl)phenyl]‐3,5‐bis(2‐pyridyl)‐4 H‐1,2,4‐triazole (apdpt), is reported, which features a reactive aminomethyl para‐substituent on the phenyl group that points “out of the back” of the triazole. This enables further functionalisation under mild conditions by using a range of esters to form an amide link. Specifically, this proof of principle study demonstrates the synthesis of apdpt successfully appended with gold‐binding thioctic acid (tpdpt), graphene‐binding/emissive pyrene/propylpyrene (prdpt/pbdpt), and a Langmuir–Blodgett film‐forming polyethylene glycol (PEG) tail (pgdpt). These ligands are subsequently reacted with [Fe(pyridine)4(NCBH3)2] to give the mononuclear iron(II) complexes [Fe(Rdpt)2(NCBH3)2]⋅solvent, in which Rdpt/solvent is tpdpt/2.5 H2O (1), prdpt/0.5 CHCl3⋅H2O (2), and pbdpt/0.5 CHCl3⋅2 H2O (3), as red powders. Magnetic studies on these powders indicate that the complexes undergo only very gradual and incomplete spin crossover, from completely or mostly high spin at 300 K, to half or three‐quarters high spin at 50 K. Gold nanoparticles are successfully functionalised with the thioctic acid tpdpt ligand to give tpdpt@Au with an average diameter (as determined by TEM) of (3.1±0.7) nm. Preliminary studies on the two pyrene systems in dimethylformamide show that upon excitation at λ=345 nm the blue fluorescence observed for the free ligands is retained, essentially unaffected, in the respective complexes.
