[Synthesis and UV/Vis spectra of a dialkyloxy substituted phthalocyanine].
A dialkyloxy substituted metal-free phthalocyanine was synthesized by using 3-(2',2',4'-trimethyl-3'-pentoxy)-1,3-diiminoisoindoles and 1,3,3-trichloroisoindolenine as starting materials, and characterized by element analysis, 1H NMR, IR and UV/Vis spectra. The dependences of wavelength of UV/Vis spectra and its split of Q band absorption on the number of substituents and, dielectric constant of solvents are discussed based on the comparison with tetraalkyloxy substituted metal-free phthalocyanine.
