Synthesis and Properties of Copper(II) Phthalocyanines with Monoazacrown and Crown Ethers as Peripheral Substituents
Preview AbstractSoluble and less soluble phthalocyaninatocopper(II) derivatives (4a and 4b) were prepared from the corresponding 7-[(4′-benzo-15-crown-5)oyl]-15, 16-dibromo-2,3,6,7,8,9,11,12-octahydro-5H-benzo[e]-[1,4,10,13,7] tetraoxaazacyclopentadecine (3a) and 7-(2′-tosylaminoethyl)-15, 16-dibromo-2,3,6,7,8,9,11, 12-octahydro-5H-benzo[e]-[1,4,10,13,7] tetraoxaazacyclopentadecine (3b) and CuCN in pyridine. A less soluble novel multifunctionalized scorpiand macrocycle-substituted phthalocyanine (4c) in which an NH2CH2CH2— chain is appended to a monoazacrown ether ring was obtained by detosylation of 4b with concentrated sulfuric acid.
Synthesis, characterization and aggregation behavior of Ni(II) and Zn(II) phthalocyanines with peripheral monoazacrown ethers
Preview AbstractThe synthesis of metallo derivatives (Ni, Zn) of phthalocyanines (pcs) obtained from 4,5-dicyanobenzomonoazacrown ether substituted with long alkyl chains (5a-d) are described. The new compounds have been characterized by elemental analysis, 1H, 13C NMR, MS, IR and UV-vis spectroscopy techniques. The aggregation properties and alkali metal interaction of the pcs (6a-d and 7a-d) were investigated.
