1,15-Bis-(2′,2′,4′-trimethyl-3′-pentoxy)phthalocyanine, a trans-form nonperipheral di-substituted phthalocyanine synthesized by the ‘cross condensation’ method
摘要:
The crystal structure of 1, 15-bis-(2',2',4'-trimethyl-3'-pentoxy)phthalocyanine was determined what confirmed the 'cross condensation' method for the ABAB type phthalocyanine and the trans-form arrangement of the two substituents suggested that the alkoxy group also affected the condensation mechanism.

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.
