“…2,2′:6′,2″-terpyridine ( tpy ) and its derivatives are important chelating ligands in coordination and supramolecular chemistry, yielding complexes with excellent electronic, optical and electrochemical properties [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Their coordination complexes, based on the cheap biocompatible and bioavailable Zn(II) metal center, were successfully used for obtaining polarized emissions [ 21 ] and emissive materials for optoelectronics and luminescence-based technologies [ 22 , 23 ], sensing and detection [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ], DNA binding and/or cleavage agents [ 34 , 35 , 36 , 37 ] and bioimaging [ 38 , 39 , 40 ].…”
