Beschreibung:
  • Four axially substituted titanium(IV)phthalocyanines of formula trans-[PcTi(OSiPh3)2], [PcTiJ{(NH)2C 6H4}], [PcTi(η2-S2)], and [PcTi=S] were prepared starting from the reactive species N,N-di-4- tolylureato(phthalocyaninato)titanium(IV). The prepared compounds were characterized by using UV/Vis-spectroscopy, FT-IR and raman spectroscopy, TGA, elemental analysis and MALDI-TOF measurements. The compound trans[PcTi(OSiPh3)2] crystallizes from chlorobenzene in the triclinic space group Pl with a = 10.41.60(8) Å, b = 11.2160(8) Å, c = 13.1495(9) Å, α = 114.124(5)°, β = 99.452(6)°, γ = 96.174(6)°, and Z = 1. [PcTiS2] crystallizes from chlorobenzene in the monoclinic space group P21/n with a = 13.114(3) Å, b = 9.752(2) Å, c = 20.975(5) Å, β = 100.46(2), and Z = 4. The crystal, structures of both compounds are discussed. The reactive ureato complex could also successfully be anchored onto SBA-15 and TiOx@SBA-15 materials using the apical ureato ligand as a good leaving group for the reaction with the silanol groups of the host material. © 2009 Wiley-VCH Verlag GmbH & Co.
