Publisher: | World Scientific Publishing Co. Pte Ltd | Abstract: | New phthalonitrile (L1), metal-free phthalocyanine (H2Pc) and zinc-phthalocyanine (ZnPc) substituted in peripheral positions with 2-pyridyl methyl pendant arm linked mixed donor macrocyclic ligands have been prepared in a multi-step reaction sequence. The novel compounds were characterized by a combination of elemental anlaysis, 1H NMR, 13C NMR, IR, UV-vis and MS spectral data. The influence of metal cations such as Cd 2+, Zn2+, Hg2+, Al3+, Fe 3+ and Cu2+ on the spectroscopic properties of dinitrile compound L1 and free phthalocyanine H2Pc was investigated by means of absorption spectrophotometry. Spectrophotometric titrations were carried out with these ligands for Cu2+ ion. The complex composition of Cu-L1 was found 1:1 by means of spectrophotometric titration data. The spectrophotometric method showed good sensitivity for Cu2+ with linear range of 2.6 × 10-6 to 1.3 × 10-4 M with dinitrile compound. © 2013 World Scientific Publishing Company. | URI: | https://hdl.handle.net/11499/8292 https://doi.org/10.1142/S1088424613500600 |
