Spectra and stabilities of α-substituted phthalocyaninatoirons
摘要:
Three aryloxy (alkoxy) alpha-substituted phthalocyaninatoirons (FePcs) were prepared and their UV-vis spectra in air or by adding of peroxide showed a new band at the red side of the Q band which can be assigned to a complexes of phthalocyaninatoirons with oxygen or peroxide. The appearance of this band related to the instability of these FePcs so their decomposition was also studied, by the benzoylperoxide oxidation. (c) 2006 Elsevier B.V. All rights reserved.
Effect of non-peripheral alkyloxy substituents on the structure and spectroscopic properties of metal-free phthalocyanines
摘要:
Four non-peripheral alkyloxy substituted metal-free phthalocyanines have been synthesized and characterized with X-ray crystal structure, IR, UV-vis and H-1 NMR. It is found that the center caves of Pc skeletons were expanded but their ring currents were reduced by the introduction of alkyloxy substituents on the non-peripheral positions.
