The esterification of carboxyl groups of deuteroporphyrin IX and transesterification of ester groups of dimethyl ester of deuteroporphyrin IX with di-, tetra-, hexaethylene glycols were studied. It is shown, that depending on the oligoethylene glycol and the reaction conditions used, both derivatives with two polyester moieties in the molecule (one for each propionate substituent) and derivatives with one polyester moiety linking the propionate substituents of por-phyrin can be obtained.

and 4-styryl-1,8-naphthalimide fragments was obtained using copper(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition click reac-tion. Excitation of BNI with 360 nm light results in resonance energy transfer (RET) in the system and formation of a fluorescence band at 617 nm which corresponds to the emission of 4-styrylnaphthalimide chromophore. Analysis of the steady-state UV-Vis absorption and fluorescence spectra showed that the efficiency of energy transfer ( Φ RET ) in the free ligand BNI was as high as 65%. The estimated Φ RET value was found to be considerably lower compared to that obtained by the theoretical calculations using the inductive-resonance Förster model (99.98%). This difference can be explained by the occurrence of photoinduced electron transfer (PET) process from the receptor group to the excited 4-alkoxynaphthalimide residue competing with energy transfer. The possibility of PET was confirmed by the quantum chemical calculations using PM6 method. Binding of silver cations by BNI in an aqueous solution at pH 7.4 (HEPES buffer) caused fluorescence enhancement at 620 nm which was related to the inhibition of PET upon com-plexation and increase in RET efficiency as a result. Coordination of Ag + with the crown ether moiety was demon-strated by the 1 H NMR spectroscopy.

In this paper, the method of cyclic voltammetry was used for the first time to study the electrochemical behavior of series of peripheral substituted cobalt phthalocyanines with consistently changing sulfonated fragments (cobalt phthalocyanine tetrasulfonic acid ( CoPcI ), cobalt tetra-4-[(6-sulfo-2-naphthyl)oxy]phthalocyanine ( CoPcII ), cobalt tetra-4-[(6,8-disulfo-2-naphthyl)oxy]phthalocyanine ( CoPcIII ), cobalt tetra-4-[(4-sulfo-1-naphthyl)oxy]-tetra-5-(1-benzotriazolyl)phthalocyanine ( CoPcIV ), cobalt tetra-4-[(1,6-disulfo-2-naphthyl)oxy]-tetra-5-(1-benzotriazolyl)phthalocyanine ( CoPcV ), cobalt tetra-4-[(1,6-disulfo-2-naphthyl)oxy]-tetra-5-(nitro)phthalocyanine ( CoPcVI ), cobalt tetra-4-{4-[1-methyl-1-(4-sulfophenyl)ethyl]phenoxy}-tetra-5-(nitro)phthalocyanine ( CoPcVII ), and cobalt octa-4,5-{4-[1-methyl-1-(4-sulfophenyl)ethyl]phenoxy}phthalocyanine ( CoPcVIII )) in an aqueous alkaline solution. Comparative analysis of the electrochemical behavior depending on the functional substitution in the macrocycle molecule was carried out. For all the compounds, central metal ion oxidation (Co 2+ → Co 3+ ) and reduction (Co 2+ → Co 1+ ) processes, as well as phthalocyanine ring activity were registered. Based on the occurrence of some peaks in the first scan numbers and the appearance/disappearance of other peaks, a hypothesis regarding the mechanism of electrodeposition of cobalt phthalocyanine derivatives at gold electrodes was formulated. It was shown that the electrodeposition process is generally independent on the nature of the substituent in the phthalocyanine macroring. It was also confirmed that react-ing species are adsorbed on the electrode surface without specific diffusion.
