Fig. S2. 1H-NMR spectrum of 5 in CDCl3
Fig. S3. 13C-NMR spectrum of 5 in CDCl3
Fig. S4. 13C{DEPT}-NMR spectrum of 5 in CDCl3, show 6 aliphatic CH2 groups and aliphatic CH group and 8 aromatic carbon
groups that completely confirmed bis-macrocycle structure
Fig. S5. ESI-MS spectra of compound 5, [M + H+] and [M + 2H]2+ molecular ions appeared at m/z = 845 and 423
Fig. S6. 1H-NMR spectrum of 7 in CDCl3

Fig. S9. Job plot for complexation of 5 with Cu(NO3)2.3H2O. Solutions of 5 (1.25 × 10–3 M) and Cu(NO3)2.3H2O (1.25 × 10–3 M)
were mixed in varying volume ratios in such a way that the total volume of each mixture was the same.

Cu(NO3)2.3H2O in the presence of 200-fold excess of MPA in the dark for 16 h in cacodylate buffer (0.1 mM,
pH 7.5), NaCl (50 mM), MPA (20 mM) at lane1 (0 mM), lane 2 (0.1 mM), lane 3 (0.2 mM), lane 4 (0.3 mM),
