chelating molecules linking the fac‐[99mTc(CO)3]+ core with targeting biomolecules are required for the development of specific diagnostic radiopharmaceuticals. Diethylenetriamine (1) and N‐(pyridin‐2‐ylmethyl)ethane‐1,2‐diamine (2) both react readily with [99mTc(H2O)3(CO)3]+ in 0.9% saline at micromolar concentrations to form the cationic complexes [99mTc(1)(CO)3]+ (5) and [99mTc(2)(CO)3]+ (6) in quantitative
A simple-structured molecule L1, a diethylenetriamine bearing two end pyrene fragments, demonstrates triple-mode fluorescence consisting of monomer and short- and long-lived excimer emissions in water, which are precisely controlled by pH and an addition of a less-polar organic solvent.

Pyrene-Containing Polyamines as Fluorescent Receptors for Recognition of PFOA in Aqueous Media
titrations highlight that protonated forms of the receptors can interact with the carboxylate group of PFOA, thanks to salt bridge formation with the ammonium groups of the aliphatic chain. This interaction induces a decrease in the fluorescence emission of pyrene at neutral and slightly acidic pH values. Similarly, emission quenching has also been observed upon coordination of PFOA by the Zn(II) complexes
