Catalytic activity of electrochemically reduced forms of mono- and diphthalocyanine complexes of transition and rare-earth
elements in the reaction of carbon dioxide with epoxides is considerably higher than that of corresponding neutral forms.
The catalytic efficiency depends on the nature of the phthalocyanine complex, the method of the catalyst immobilization, and
the electrophilicity of epoxide.

New 2,9,16,23-tetra[o-(hydroxymethyl)benzyloxy]-substituted phthalocyanines were synthesized. Their reaction with 4-bromopyridine afforded 2,9,16,23-tetra[o-(4-pyridyloxymethyl)benzyloxy]-substituted analogs, treatment of which with HCl led to water-soluble pyridinium salts. Spectroscopic
properties of the phthalocyanines obtained were studied and a hypsochromic shift of the Q-band of the hydrochloride as compared
with the corresponding pyridinium analogs was observed.

A number of naphthalocyanine and dinaphthalocyanine complexes of the rare-earth elements based on 6,7-bis(phenoxy)-2,3-naphthalodinitrile
obtained for the first time has been synthesized and their spectral properties have been investigated. Electrochemical behavior
of lutetium [bis(octaphenoxy)naphthalocyanine] in the thin hydrophobic films has been studied.

A new method for the preparation of 3,5-dimethyl-o-phthalodinitrile was proposed, and the substituted diphthalocyanine complexes of LuIII, TmIII, ErIII, and DyIII were synthesized. The spectral and electrochemical characteristics of the complexes were found. The complexes can be used as materials for electrochromic devices with high contrast. 相似文献

Cobalt(II) porphyrazine is synthesized and studied as an active component of a polyvinyl chloride plasticized membrane ion-selective electrodes (ISEs). It is established that regardless of their structure, ISEs are sensitive to iodide. The introduction to the ISE of an ionic additive, ionic liquid 1,3-dihexadecylimidazolium chloride, significantly improves the electrochemical characteristics: the slope of the electrode function reaches ?(57 ± 1) mV/dec, cmin = 8.3 × 10–6 M. Solid-state screen-printed electrodes the surfaces of which are modified by a 1: 4 mixture of cobalt(II) porphyrazine and ionic liquid 1,3-dihexadecylimidazolium chloride demonstrate satisfactory electrochemical characteristics: the slope of the electrode function is ?(56 ± 4) mV/dec and cmin = 2.5 × 10–5 M. The potentiometric selectivity of the ISEs for iodide is studied. It is found that the effect of lipophilic interfering ions is significantly lower for solid state ISEs than for plasticized membrane electrodes. 相似文献
