Compound 1 (1.75 g, 2.33 mmol) and thioacetic acid (0.25 mL, 3.50 mmol) and were added, and the mixture was stirred at 0 °C for 2 h followed by stirring overnight at RT. All volatiles were removed in vacuo. Purification was performed on silica gel (eluent petroleum ether b.p. 40-60 °C: ethyl acetate: triethylamine; 4:5:1, v/v/v, Yield was 2.8 g (76, 1H-NMR, CDCl3, δ 8.70 (1H, s, 8.55 (2H, d, J 7.7, 7.86 (4H, m, 7.58 (4H, m, 4.19 (4H, s, 3.73 (8H, s, 3.70 (12H, s, 2.96 (2H, t, J 6.8, 2.35 (3H, s, 1.76 4H, m

    • Synthesis of 2,2′,2″,2‴, 4′-[4-(6-mercaptohexynyl)phenyl, 2, 2″:6′,2″-terpyridine-6,6″-diyl]bis, methylenenitrilo)}tetrakisacetic acid europium(III, 3, Compound 2 (0.10 g, 0.10 mmol) was dissolved in methanolic potassium hydroxide (20 μL, 0.5 mmol) and the mixture was stirred for 2 h at RT and concentrated. The residue was dissolved in water, and the pH was adjusted to 6.5 with aq. HCl. Europium(III) chloride hexahydrate (55 mg, 0.15 mmol; predissolved in 0.1 mL of water) was slowly added, and the mixture was stirred for 1 h at RT, after which pH was raised to 10 with 0.1 M NaOH. The europium hydroxide formed was removed by centrifugation, and the solvent was removed in vacuo. The residue was dissolved in water (1 mL) and extracted with phenol 0.5 g, The aqueous layer was discharged, and the phenol and the product were partitioned between diethyl ether and water. The aqueous phase was washed with diethyl et
