Özet

Metal-free phthalocyanines and metal phthalocyaninates (M = Ni, Cu, Co or Zn) carrying eight alkylthio-groups on peripheral positions have been synthesised from 4,5-bis(alkylthio)phthalonitrile and 1,8-diazabicyclo[5.4.0]undec-7-ene (dbu) or the corresponding anhydrous metal salt [NiCl2, CuCl, CoCl2 or Zn(O2CMe)2]. The resulting compounds reacted with silver(I) or palladium(II) salts to form complexes with a phthalocyanine:metal ratio of 1:4. Spectrophotochemical investigation of these reactions revealed that complexation with Ag(I) results in aggregation, while the addition of Pd(II) destroys the aggregation and yields a new Q band at 720 nm.
