New highly soluble phenoxy-substituted phthalocyanine and azaphthalocyanine derivatives: Synthesis, photochemical and photophysical studies and atypical aggregation behavior
Original language description
A series of zinc phthalocyanines and corresponding aza-analogues azaphthalocyanines substituted with peripheral 2,6-diisopropylphenoxy substituents containing different functional groups (Br, OCH3, and OH) were synthesized and their photophysical properties were investigated. UV-vis and H-1 NMR analyses confirmed the non-aggregation behavior of the prepared complexes in most organic solvents. All investigated compounds showed good photophysical and photochemical properties in THF and DMF with Phi(F) values in the range of 0.22-0.44 and Phi(Delta) values ranging between 0.42 and 0.57. Hydroxylated compounds showed good solubility in polar solvents including ethanol, methanol, acetone and even in aqueous ethanol mixtures. Absorption spectra in aqueous ethanol indicated presence of only monomers even at very low ethanol content in water (0.5% of ethanol in water). Despite this, no fluorescence occurred from approximately 50% of ethanol in water suggesting presence of aggregates that do no
