摘要: Abstract Novel water soluble free-base, Zn(II) and Co(II) metallo phthalocyanines with four cinnamic acid moieties were prepared from the corresponding tetrakis(7-coumarinthio-4-methyl)-phthalocyanine by lactone ring opening reaction. The new compounds purified characterized elemental analysis, 1H NMR, Maldi-TOF, FT-IR UV–Vis spectral data. Cyclic differential pulse voltammetry in situ spectroelectrochemistry of 2,9,16,23-tetrakis(7-coumarinthio-4-methyl) substituted free-base 1a, 1b 1c phthalocyanines, employed as starting have been studied. This allowed us not only to identify metal- phthalocyanine ring-based redox processes complexes, but also effect aggregation on these processes.
